Answer 1

Answer:

1) 55:63, ii) 54:49

2) I) 8:14 and 12:21

Step-by-step explanation:

1 I) (5:9)/(7:11) = (5/9)÷(7/11) = 5/9×11/7 = 55/63 or 55:63

ii) (6:7)/(7:18) = (6/7)÷(7/9) = 6/7×9/7 = 54/49 or 54:49

2 I) 4:7 = 4/7 (multiply the numerator by any same number)

Ex - 4/7×2/2 = 8/14 = 8:14

4/7 × 3/3 = 12/21 = 12:21

solve the other 2 similarly
