In a recent poll of 2,000 households, 29% had pets. how many households did not have pets

29% had pets, to find out how many didn't, we subtract 29% from 100%
100 - 29 = 71
To turn a percentage into a decimal (multiplier) we divide by 100
71/100 = 0.71
Finally, multiply 0.71 by the original amount
0.71 x 2000 = 1420
1420 households did not have pets
