Question

c. 45: 9:: x: 7
f. 13:7:: X: 21
ortional or not:​

Answer 1

Answer:

1) x = 35

2) x = 39

Step-by-step explanation:

1) 45 : 9 :: x : 7

Product of extremes = Product of Means

= 45 × 7 = 9 × x

= 315 = 9x

x = 35

2) 13 : 7 :: x : 21

Product of extremes = Product of Means

= 13 × 21 = 7 × x

= 273 = 7x

x = 39
