7 /12

Answer 1

that's wrong

Answer 2

To find out how much gas is in the tank, we need to find 5/8 of 12 gallons.
To find 5/8 of a number, we can multiply the number by 5 and then divide it by 8.
5/8 of 12 gallons can be calculated as (5*12)/8 = 60/8 = 7.5 gallons.
Since the gas tank cannot have half a gallon, we round down to the nearest whole number which is 7 gallons.
Therefore, the answer is 7 gallons.

Answer 3

Apologies for the incorrect response. Let's try again.

To find out how much gas is in the tank, we can multiply the capacity of the tank (12 gallons) by the fraction representing how full it is (5/8).

12 gallons * 5/8 = (12 * 5) / 8 = 60 / 8 = 7 4/8 gallons.

We can simplify 7 4/8 as a mixed number by dividing the numerator and denominator by their greatest common divisor, which is 4 in this case.

When we divide 4 into both 4 and 8, it simplifies to 1/2.

Therefore, the answer is 7 2/4 gallons, which can also be simplified as 7 1/2 gallons. So, the correct answer is 7 1/2.
