Question

(? % of 99) +0.9 = 16.5​

Answer 1

Answer:

15.76

Step-by-step explanation:

Let us say that the number is x.

Then,

(x % of 99) + 0.9 = 16.5

(x/100 × 99) + 0.9 = 16.5

99x/100 = 15.6

x = (15.6 × 100)/99 = 15.76

Answer 2

Answer:

let (x% of 99) + 0.9= 16.5

x × 99/100 = 16.5 - 0.9

x × 0.99 = 15.6

x = 15.6/0.99

x= 15.57
