Question

The lightest puppy in a litter weights 9 ounces ,which is 3/4 of the weight of the heaviest puppy .the Equation 3/4w =9 can be used to find the weight w on ounces of the heaviest puppy.how much doest the heaviest puppy weight ? use two strategies and write at least two equivalent equation.

Answer 1

so 3/4w=9
clear fraction
multiply both sies by 4/3 to clear fraciton
4/3 times 3/4 times w=9 times 4/3
12/12 times w=36/3
w=12


another way is 3/4w=9
multiply both sies by 4
3w=36
divide both siedes by 3
w=12
