Question

How do you find what number to multiply/divide to find equivalent fractions??? The only strategy i know if cross multiplication but my teacher said i have to know how to do it without that strategy go

Answer 1

Well, first find a number that both denominators in the fraction share, then you multiply whatever number it takes to get that and then multiply the same number to the numerator. Hope this helps!

Answer 2

When multiplying u can multiply with any numbers
When dividing you will have to find the LCF of the numeratir and denominator, least common factor, that is not 1,
Example 4/10

4: 1,2,4
10:1,2,5,10
2 is the LCF
4/10 divided bu 2/2 = 2/5
hope it helped
