Question

on sunday, Antonio spent a total of 3 1/4 hours driving and 1 3/4 hours gardening. How much longer did he spend driving than gardening? write as a mix number.

Answer 1

I find it easier convert 1/4s in decimals so first I would turn 3 1/4 into 3.25 and 1 3/4 into 1.75.

3.25-1.75 is 1.5

Convert back into a decimal and it is 1 1/2

So, Antonio spent an hour and a half more on driving then gardening.

Answer 2

1 1/2 hours

Explanation:

Time spent by Antonio in driving = 3 1/4 = 13/4

Time spent in gardening = 1 3/4 = 7/4

In order to find how much he spend driving than gardening, we can subtract 13/4 and 7/4.

`(13)/(4)-(7)/(4)`

Te denominator is same. So, we can directly subtract the numerators.

`(13-7)/(4)\\\\=(6)/(4)\\\\=(3)/(2)=1(1)/(2)`

Therefore, Antonio spent 1 1/2 hours more in driving than gardening.
