Question

Dan drink 3/8 of milk for breakfast
4/5 for dinner how much in total he drink

Answer 1

For this case we must add the fractions:

Milk for breakfast:
`\frac {3} {8}`

Milk for dinner:
`\frac {4} {5}`

So, we have:

`\frac {3} {8} + \frac {4} {5} = \frac {3 * 5 + 8 * 4} {5 * 8} = \frac {15 + 32} {40} = \frac {47 } {40}`

Thus, Dan drank
`\frac {47} {40}` of milk in total.

Answer:

Dam drank
`\frac {47} {40}` of milk in total.
