Answer:

This is a shortcut if you want avoid long multiplication.

First, you have to examine the equation if it can be cancelled out.

13. (20)(⅘)=16, if you notice 20 is a multiple of 5 from the fraction ⅘, just divide it so it will now be 4 then multiply it by 4

14. 18/9=2x2=4

15. 64/8=8x5=40

so on..
