Question

Braden's family had 1 and one-third gallons of milk in the refrigerator before dinner. After dinner, they had finished three-eighths of the milk. How many gallons of milk did they drink at dinner?

Answer 1

1 1/3 gallons = 4/3 gallons

3/8 of 4/3 =
3/8 * 4/3 = 12/24 = 1/2

They drank 1/2 gallon

Answer 2

no they didn't

Answer 3

(3/8) / (1/2) = (5/8) / x
cross multiply
3/8x = (1/2)(5/8)
3/8x = 5/16
x = (5/16) / (3/8)
x = 5/16 * 8/3
x = 40/48
x = 5/6

so 3/8 is 1/2
5/8 = 5/6

1/2 + 5/6 = 4/3
3/6 + 5/6 = 8/6
8/6 = 8/6 (correct)

They drank 1/2 gallons leaving 5/6 gallons left.

Answer 4

@wio ...can you take a look at this. Am I doing something wrong

Answer 5

Let's see... well

Answer 6

Your answer looks correct.

Answer 7

I would write it as: \(4/3 \cdot (1-3/8)\).

Answer 8

Answer 9

basically, it is just asking what is 3/8 of 1 1/3 gallons..right ?

Answer 10

oh wait, never mind... it is just 1/2
