How do you find missing fractions?

How do you clear fractions?
I am not entirely sure what you mean with "clear". But if you want to get rid of fractions in an equation, you can multiply both sides of the equation by the least common multiple of the fractions. For example, take the equation: (1/2)x + 3 = (1/5)x If you multiply both sides by 10, you get: 5x + 30 = 2x
How do you multiply fractions with uncommon denominators?
To multiply fractions all you do is multiply the numerators and the denominators separately eg: 4/7 x 6/11 = 24/77. The "commonality" of denominators has no relevance.
When do you cross multiply in dividing fractions?
To divide fractions, turn the second one over - that is, swap its numerator and denominator - and multiply. Nothing else is necessary. You cross multiply when you have a proportion, that is when you have two ratios that are equal.
How do you get a fraction of another fraction?
To get a fraction of another fraction you have to multiply the fractions. To multiply fractions, just use this simple algorithm: Step 1-Turn all whole numbers and mixed numbers into improper fractions. Step 2-Multiply the numerators of the 2 fractions. The answer to that problem will be the numerator of the answer. Step 3-Multiply the denominators of the 2 fractions. The answer to that problem will be the denominator of the answer. Step 4-Reduce.
What does it mean to multiply and divide fractions?

How you multiply fractions?
Best shown with an example. 2 2/3 X 4 1/5 #1 Convert to improper(top heavy) fractions. 8/3 X 21/5 #2 cancel down (reduce) were possible. In this case by '3' 8/1 X 7/5 #3 multiply the numerators(top) and multply the denomiaotor(bottom) and place the numerator over the denomiator 56/ 5 #4 Convert to a mixed fraction 11 1/5 The answer. !!! Hope that helps!!!!
What fractions have the same value?
5/10 is equal to 1/2. Whatever you multiply the numerator by you must multiply the denominator and you will always get same valued fractions
How can you use models to multiply fractions?
No, you cannot use models to multiply fractions!!
What are the rules for multiplying fractions?
When multiplying 2 fractions, we multiply the two numerators together and the two denominators together.
How do you find volume with fractions?
You multiply the fractions
What is the difference between cross and across?
When you add or subtract fractions you cross multiply and when you multiply or divide fractions you across multiply.
How can you find out halves of fractions?
Multiply them by 1/2 and you have half of the original fraction.
Do you multiply the denominator when you multiply fractions?
Yes you do.
Do you need common denomonators when mutiplying fractions?
No, you do not need to find a common denominator when multiplying fractions. To multiply fractions, you simply multiply the numerators together and the denominators together. However, finding a common denominator can be helpful when simplifying the resulting fraction.
Why do you invert fractions?
When you divide by fractions, you invert and multiply.
