Ian drinks 3 \text { pints}3 pints3, start text, space, p, i, n, t, s, end text of water during a long hike. He drinks 1\dfrac12
r-ruslan [8.4K]

Answer:

Total = 7\frac{1}{2} cups

Step-by-step explanation:

Given

Initially, he drank 3 pints of water

Then, 1\frac{1}{2} more cups

Required

How many cups did Ian drink altogether

This question can be solved by adding the size of water he drank during the hike and when he got home

i.e.

Total = 3\ pints + 1\frac{1}{2} cups

But the answer should be in cups;

So, number of pints has to be converted to number cups

Given that 1 pint = 2 cups;

3 pints will be 3 * 2 cups

3 pints = 6 cups;

So,

Total = 3\ pints + 1\frac{1}{2} cups

Total = 6\ cups + 1\frac{1}{2} cups

Total = 7\frac{1}{2} cups

Altogether, he drank 7\frac{1}{2} cups of water
