Question

The sum of two number is 45 and their ratio is 7 ratio 8 the number hours

Answer 1

Answer:

Numbers are 21 and 24

Step-by-step explanation:

if the ratio of two no. is 7:8

then the no. are 7x and 8x

as ratio is 7:8

now their sum is 45

i.e 7x + 8x = 45

15x = 45

x=3

hence no. are 7×3=21

and 8×3=24

Answer 2

Answer:

numbers are 21 and 24

Step-by-step explanation:

let 7x and 8x be the numbers where x is a common factor of both

then,

7x+8x=45

15x=45

15x÷15=45÷15 (division by 15 on both sides)

x=3

hence,

7x=7×3=21

8x=8×3=24
