Answer:

1. r = 28

2. k = 45

3. s = 40

4. f = 14

5. h = 18

6. n = 5

Explanation:

1.

7/r = 1/4

1 × r = 4 × 7

r = 28

2.

15 × k = 9 × 75

15k = 675

k = 45

3.

21 × s = 24 × 35

21s = 840

s = 40

4.

17 × f = 7 × 34

17f = 238

f = 14

5.

5 × h = 15 × 6

5h = 90

h = 18

6.

14 × n = 5 × 42

14n = 210

n = 5
