When do you cross multiply to solve an equation?
When doing fractions, you may cross multiply.
How do you find missing fractions?
U can multiply
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?
multiply and divide fractions!-.-
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
What are the rules for multiplying fractions?
When multiplying 2 fractions, we multiply the two numerators together and the two denominators together.
How can you use models to multiply fractions?
No, you cannot use models to multiply fractions!!
How do you find volume with fractions?
You multiply the fractions
How can you find out halves of fractions?
Multiply them by 1/2 and you have half of the original fraction.
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.
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.
What are 2 ways you can tell that two ratios can form a proportion?
1. They are equivalent fractions.2. They cross-multiply to the same value (a/b = c/d if and only if ad = bc).1. They are equivalent fractions.2. They cross-multiply to the same value (a/b = c/d if and only if ad = bc).1. They are equivalent fractions.2. They cross-multiply to the same value (a/b = c/d if and only if ad = bc).1. They are equivalent fractions.2. They cross-multiply to the same value (a/b = c/d if and only if ad = bc).
Do you multiply the denominator when you multiply fractions?
Yes you do.
When you multiply two fractions why is the product smaller than the fractions?
if 1/2 x 1/3 then times it and get 1/6
