32 is 80% of 40

35% of 60 is 21

Step-by-step explanation:

For the first 4 situations, you need to multiply the first number by the reciprocal of the percentage as a fraction, which would be 100/(percent). Here's an example:

12 is 20% of x

x = 12*(100/20)

100/20 was used because that is the reciprocal of 20/100, which is 20% as a fraction out of 100.

For the last 4 situations, you just need to multiply the number by the percentage as a decimal. For example:

35% of 60 is x

x = 60*.35
