A builder takes ¾ of an hour to lay 50 tiles. a. How many tiles can he lay in 4 ½ hours? b. If he works 6 ¾ hours a day, five times a week, how many tiles can he lay that week?

Question

Can anyone help? please

Answer 1

4 1/2 divided by 3/4 = 9/2 divided by 3/4

= 9/2 x 4/3 = (9/2)(4/3) = 36/6 =6

He does 6 times as much in 4 1/2 hours as in 3/4 of an hour or 6 x 50 = 300 tiles in 4/12 hours

6 3/4 divided by 3/4 = 27/4 divided by 3/4 = 9

9 times as much is 9 x 50 = 450 tiles in 6 3/4 hours

5 x 450 = 2250 tiles in a 5 day work week
