Question

31.   Hiram raises earthworms. In a square of compost 4 ft by 4 ft, he can have 1,000 earthworms. How many earthworms can he have if his square of compost has a side length that is 5 times longer?  (1 point)

anonymous · Answer

find the area= 4 * 4 = 16 ft^2
and if the side is 5 times longer then, 4(5) * 4(5) = 400ft^2

Use ratio
if     16ft^2   =   1000 worms
then 400ft^2  =     x worms?

1000*400/16 = x
