32 is 20% of what number?

22 is 40% of what number?

55

32 is 20% of what number?

160

Step-by-step explanation:

If 22 is 40% of a number you can divide 22 by 40 to find what one % would be.

22/40=.55

To find what the whole number is we can multiply that by 100, since we want 100% of the number we have is only 1%.

.55x100=55

Check:

40% of 55= 55x.4=22

Repeat this for the next problem.

32/20=1.6

1.6x100=160

Check:

160x.2=32

its the fourth option
