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

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

Answer 2

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!
