Tonya Said:Math Question, adding fractions and stuff like that...?We Answered:1. You multiply the numerators and denominators together... ex. 1/2 X 1/2 = 1/4
2. Change the mixed number into a improper fraction and then multiply
3. Change into improper fractions and then multiply
4. Add the numerators together and then add the numbers in front of the fraction together... ex. 2 1/2 + 2 1/2 = 4 2/2 = 5
5. Change the mixed numbers into improper fractions and then the LCD. Add fractions together.
6. Change into improper fractions and then get the LCD (I think) then subtract
7. Take the number and multiply...
Joseph Said:Writing Parallel Resistors/ adding and subtracting fractions?We Answered:1/R(total) = Sum(1/R(n))
where n = 1 to number of parallel resistor
R(total) = 1/Sum(1/R(n))
where n = 1 to number of parallel resistorJane Said:What are the biggest problem people face when adding and subtracting fractions?We Answered:Fractions is really easy... What makes it difficult is the operations... People get all mixed up with subtracting and adding fractions or even dividing or multiplying fractions. The thing you got to know is. When you add or subtract a fraction, find the common denominator. For divding fractions you will want to convert it into a multiplication fraction...
Aaron Said:Whats the fastest way to order fractions percents and decimals?We Answered:you should convert all to the same form, that is, all fractions (hardest), or all decimals (easiest) or all percents (dopiest).
Then put them on a number line. Of course, more to the left is less than a number to the right.
Negatives go to the left, the bigger the absolute value, the more to the left.
Hope this helps.Kirk Said:Math Help, Decimals, Percents, Fractions, and a Pie Chart!!!!?We Answered:ok lets say your percent is 170%. well the decimal is after the 0. right? right! so you move...

y = -1Jamie Said:Homework help?! Fractions!?We Answered:In each case, the problem has identified the two parts to be compared, such as Kristi's titles and Katrina's titles. The ratio is simply the two integers with a slash between them. For instance,
3 / 6
is the answer to that problem. Where are you having trouble with the basic concept? Are you confused by the few times you need to add two things together, or is this a reading comprehension problem? Since you haven't described that, I'm hopeful that the one example...
Gladys Said:Primary school teachers !! Maths lesson ideas - fractions Year 3?We Answered:I actually teach fractions in grade 2. We start off by folding paper into different configurations. We then shade these pieces of paper to look like the different fractions. The hardest part of learning fractions is being able to see the different fractions.Greg Said:How do you do lesson 2 fractions and mixed numbers ?We Answered:What's lesson 2?

Timothy Said:How do you multiply fractions and mixed numbers?We Answered:First, convert the mixed number to an improper fraction. Next, multiply the numerators and the denominators. Then, simply the result into a mixed number.
Example: 3 2/3 * 4 7/8
1) Convert to 11/3 * 39/8
2) Multiply the numerators and the denominators 429/24
3) Simplify to a mixed number: 17 21/24, simplified to 17 7/8Marian Said:How do you divide fractions/ mixed numbers/ whole numbers?We Answered:If the answer is a mixed number or whole number change it to a fraction. For example: 3 2/4 would be changed to 14/4 or 2 would be 2/1....
Joel Said:What is the difference between adding and multiplying fractions?We Answered:When you add the fractions you have a common denominator (or work toward it) and add the numerators.
For example, 1/2 + 3/5 = 5/10 + 6/10 or 11/10
When you multiply you multiply the numerators across, and then multiply the denominators across
1/2 * 3/5 = 3/10Carole Said:Help with multiplying fractions with different signs (positive and negative)?We Answered:Just mutiply the numerator and denominator respectively no matter the number is negative or positive.

Perry Said:reducing fractions?We Answered:I would need to see actual problems. Remember, some fractions cannot be reduced. Any fraction that can be reduced, you must use the highest # that goes into both numbers. Also, when multiplying fraction, you flip the second set of numbers and if you have two sets of the same # (diagonal only) then you cross cancel them and make them a 1.Billie Said:Reducing fractions?We Answered:1) 4

Wilma Said:What are the steps to subtracting fractions with different denominators?We Answered:(a/b) + (c/d) = (a*d + c*b)/b*d
e.g
(2/3) + (7/13) = (26+21)/39 = 47/39Seth Said:When figuring out subtracting fractions and mixed numbers, how do you determine any common denominator?We Answered:common denominator could be found by taking l.c.m of those denominators.
Ex: 3 2/7 + 4 5/6
now we just add the whole number 3+ 4= 7
now we take 2/7 + 5/6
l.c.m of 7 and 6 is 42
2*6/7*6 + 5*7/6*7
12 +35/42
47/42
1 5/42
so the whole number 3 + 1 = 4
= 4 5/42
