The lightest puppy in a litter weighs 9 ounces, which is 3/4 of the weight of the heaviest puppy. The equation 3/4 w + 9 can be used to find the weight w in ounces of the heaviest puppy. How much does the heaviest puppy weigh?
I think you meant to write 3/4W = 9 to get rid of the denominator, multiply both sides by the denominator. 3W = 36 now divide both sides by 3 W = 12 the answer is 12 ounces.
