​

Answer 1

Answer:

1. (c) 4:7 2.(c) 23

Step-by-step explanation:

1. No. of vowels = 4

No. of consonants = 7

Ratio = 4:7

2. 9/5 × 36/x-3

9(x-3) = 5×36

x-3 = 5×36/9

x-3 = 20

x = 20+3

x = 23

Answer 2

Answer:

(B) 4:7

(C) 23

Step-by-step explanation:

5*369 = 9* (x-3)

180 = 9x -27

9x = 180 + 27

9x = 207

x = 23
