Question

Mr. Neville Iceguy mixed up 12 3/5 gallons of chili for a party. If 7 3/4 gallons of chili was mild, and the rest was extra spicy, how much extra spicy chili did Mr. Iceguy make?

Answer 1

`4(17)/(20)`

Explanation:

We have been given that Mr. Neville Iceguy mixed up 12 3/5 gallons of chili for a party. 7 3/4 gallons of chili was mild.

To find the amount of extra spicy chili, we will subtract amount of mild chili from total chili as:

`12(3)/(5)-7(3)/(4)`

Convert mixed fraction into improper fraction:

`12(3)/(5)\Rightarrow (12* 5+3)/(5)=(60+3)/(5)=(63)/(5)`

`7(3)/(4)\Rightarrow (7* 4+3)/(4)=(28+3)/(4)=(31)/(4)`

`12(3)/(5)-7(3)/(4)\Rightarrow(63)/(5)-(31)/(4)`

Make a common denominator:

`(63*4)/(5*4)-(31*5)/(4*5)`

`(252)/(20)-(155)/(20)`

Combine numerators:

`(252-155)/(20)`

`(97)/(20)`

`4(17)/(20)`

Therefore, Mr. Iceguy made
`4(17)/(20)` gallons of extra spicy chili.
