John has 1 ½ hours of homework each day from Monday through Friday and 2 ¾ hours over the weekend. How much work does John have in a week?

10.25 (10 1/4)

Step-by-step explanation:

1 1/2 = 1.5

Monday through Friday = 5 days.

1.5 hours of homework times 5 = 7.5

2 3/4 = 2.75 (his homework over the weekend)

7.5 plus 2.75 = 10.25

John would have 10.25, or 10 1/4 hours in a week.

1/4 + 1/7 = 1/x rate

Common denominator = 28x

7x + 4x = 28

11x = 28

x = 28/11

x = 2.54 hours

x = 2hrs 32mins 44secs.

Hope this helps.
