Question

Hank used 3 1/2 bags of seeds to plant grass in the front yard he used three times as much seed to plant grass backyard how much seed did Hank need for,the back yard

Answer 1

If he used three times the first amount, you need to multiply the first number by three:

3 1/2 x 3
Also 3.5 x 3
= (3 x 3) + (0.5 x 3)
= 9 + 1.5
=10.5

Therefore Hank needed 10.5 bags of seeds to plant the grass in the back yard.
