Question

Mikes milk shakes had a total of 9 gallons of ice cream they used 3 3/9 gallons this week and 1 1/3 gallons last week how many gallons of ice cream do they have left

Answer 1

Answer: 4

Explanation:

`9-(3(3)/(9) + 1(1)/(3) )\\9-((30)/(9) + (4)/(3))\\ 9-((10)/(3)+ (4)/(3))\\ 9-((14)/(3) )\\= ((9)(3)-14)/(3) \\= (27-14)/(3) \\=(13)/(3)\\ \\or\\\\4 gallons`

or

=
`4(1)/(3)`

approximately

Answer 2

Explanation:

`3 (3)/(9)=(3 * 9+3)/(9)=(30)/(9)=(10)/(3)\\1(1)/(3)=(1* 3+1)/(3)=(4)/(3)\\Total~used=(10)/(3)+(4)/(3)=(14)/(3)\\Left~over=9-(14)/(3)=(9 * 3-14)/(3)=(13)/(3)=4 (1)/(3)~gallons`
