Sagot :

Answer:

For 18 : 24 = n :60

Answer: n = 45

For 36 : n = 4 : 1

Answer: n = 9

For 105 : n = 45 : 3

Answer: n = 7

Solutions:

For 18 : 24 = n :60

18 : 24 = n :60

(24) (n) = (18) (60)

24n = 1080

24n / 24 = 1080 / 24

n = 45

For 36 : n = 4 : 1

36 : n = 4 : 1

(n) (4) = (36) (1)

4n = 36

4n / 4 = 36 / 4

n = 9

For 105 : n = 45 : 3

105 : n = 45 : 3

(n) (45) = (105) (3)

45n = 315

45n / 45 = 315 / 45

n = 7
