A company makes 120 bags. 40 of the bags have buttons but no zips.
43 of the bags have zips but no buttons.
33 of the bags have neither zips nor buttons.
How many bags have zips on them?

47 bags

Step-by-step explanation:

A company makes 120 bags.

40 of the bags have buttons but no zips.

43 of the bags have zips but no buttons.

33 of the bags have neither zips nor buttons

so

120 total bags - 40 (no zips) - 33 (neither zips nor buttons) = 47

therefore

the number of bags that have zips on them is 47 bags.

step-by-step explanation:

the multiplicative inverse of a fraction a/b is b/a. for the multiplicative inverse of a real number, divide 1 by the number. for example, the reciprocal of 5 is one fifth 1/5 or 0.2, and the reciprocal of 0.25 is 1 divided by 0.25, or 4.
