Step-by-step explanation:

6. 5 : 6 = 10,450

5n + 6n = 10,450

11n = 10,450

11 11

n = 950

worker #1 = 5(950) = 4,750

worker #2 = 6(950) = 5,700

7. 4 : 5 = 108

4n + 5n = 108

9n = 108

9 9

n = 12

men 4(12) = 48

women 5(12) = 60

8. 2 : 3 = 425

2n + 3n = 425

5n = 425

5 5

n = 85

Math Books 2(85) = 170

Other Books 3(85) = 255

9. 1 : 2 : 3 = 576

1n + 2n + 3n = 576

6n = 576

6 6

n = 96

boy 1(96) = 96

boy 2(96) = 192

boy 3(96) = 288

10. 1 : 45 = 414

1n + 45n = 414

46n = 414

46 46

n = 9

1 (9) = 9 teachers

45(9) = 405 pupils
