Question

the sum of two number is 90 and they are in the ratio of 7 : 8. find the numbe​

Answer 1

Answer:

let the ratios of numbers be 7x and 8x

then, 7x + 8x = 90

=> 15x = 90

=> x = 90/15

=> X = 6

hence, first numbers = 7x6 = 42

second number = 8 x 6 = 48

Answer 2

Step-by-step explanation:

let x be the ratios,

so,

7x + 8x = 90 (because the sum of ratios = 90)

15x = 90

x = 90/15

x = 6

now we can easily find ratios ,

7 × 6 = 42

8 × 6 = 48

so the two number are 42 , 48
