Please explain to me how 3.2÷4=0.8 is done
DedPeter [7]

To make it easier just assume there is no decimal point then just work out the 32÷4 where we know that 4 goes into 32 8 times so you get 8 remember the decimal point and since it was one decimal place you will push the decimal over to the left of 8 and that is how you get 0.8

A 400 gallon swimming pool is being drained. After three hours, 250 gallons have been drained. If the rate of drainage continues
Nezavi [6.7K]
If you would like to know how long will it take to drain the pool, you can calculate this using the following steps:

3 hours ... 250 gallons
x hours = ? ... 150 gallons (= 400 - 250)

3 * 150 = 250 * x
x = 3 * 150 / 250 
x = 1.8 hours

3 hours + 1.8 hours = 4.8 hours

The correct result would be B. 4.8 hours.
