Answer 1

Mike needs 17 more hours

Maria consumed 41/270 I each day.

The number that gives 2 4/5 when multiplied by 2 1/3 is 1 1/5

Explanation:

5.) 2/3 = .66666666 (it goes on)

25.50 = .6666666 = 17

6.)

1/3 : 5/7 = 1 : ?

5/7 × 1 = 5/7

5/7 / 1/3

= 15/7

=2 1/7

7.) 5 7/9 / 45 = 52/405

8.) 4 5/9 / 30 = 41/270

9.) 25 / 1 2/3 = 15/1 = 15

10.)

5 × (3-1) / 1

5 × 2

10 days

11.) 2 4/5 / 2 1/3 = 6/5 = 1 1/5
