Question

The sum of two numbers is 45 and their ratio is 7: 8. The two numbers are

Answer 1

Answer:

21 and 24

Step-by-step explanation:

Let, the first number be = 7x   [Where x be a common factor]

the second number be = 8x

Therefore, sum of two numbers = 45

or, 7x + 8x = 45

or, 15x = 45

or, x = 45/15 = 3

Therefore, the first number is = 7x = 7*3 = 21

the second number is = 8x = 8*3 = 24

Answer 2

Answer:

the numbers are 21 and 24

Step-by-step explanation:

given:

sum of 2 numbers is 45.

the ratio is 7:8

So,

let the 2 numbers be 7x and 8x resp.

7x + 8x = 45

15x = 45

x =45/15

x = 3.

therefore ;

7x = 7 × 3

=21

8x = 8 × 3

24

hence the numbers are 21 and 24
