Numerators and denominators are just numbers. List the factors of each and circle the numbers that appear on both lists. These are common factors.
Using my knowledge of greatest common factors and the distributive property, I can tell that 45 + 63 is equal to 9(5 + 7) or 9 x 12, which is 108. Of course, I could also tell that from my knowledge of addition.
Infinitely many ways, since if you have found one way then take one of the fractions and replace it by an equivalent fraction. Repeat for ever.
0.031 = (0 x 1) + (0/10) + (3/100) + (1/1000)
You have to write all the factors of 4, then all of the factors of 6. For example the factors of 4 are: 1,2,4. And the factors of 6 are: 1,2,3,6. Then you find the largest number that is a factor of both! In this case the GCF or greatest common factor would be 2!
Factor the numerator and denominator, and then cancel any common factors.
write two equivalent fractions to one sixth?
Change them to improper fractions and double them.
Answer: When adding or subtracting fractions with different denominators it is important to change the denominators into the lowest common denominator by using equivalent fractions. Answer: Equivalent fractions are used to: * Simplify fractions. It is sort of inelegant to write the final solution of a problem as 123/246, when you can just as well write it as 1/2. * Add fractions. If two fractions have different denominators, you need to convert them to equivalent fractions that have the same denominator. Only then can you add. * Subtract fractions (same as addition). * Compare fractions, to check which one is larger (same as addition).
No. There are infinitely many equivalent fractions for any given fraction.
3/10 = 30/100
use your pattern to write a rule for equivalent fractions
multiply the denominators
They are: 14/16 and 21/24
They are: 16/18 and 24/27
