Change 3 1/2 to 3 3/6 and change 4 1/3 to 4 2/6.

Add 3³/6 and 4²/6 to get 7 5/6.

Subtract 7 5/6 from 10 to get 2 1/6.

2. C

Simply double the amount of water needed in the recipe for 2 people to get the amount of water needed for 4 people.

1: you turn %15 into a decimal by moving the decimal point two places to the left.

2: and then you multiply .15 by 1,200 , which will get you 180.00

3: from there you will add 180 to 1,200

4: which will get you 1,380
