Question

the sum of 2 numbers is 405 find their ratios is 8 : 7 find the number ​

Answer 1

Step-by-step explanation:

let 8x ànd 7x be 2 ño.

then

ÀTQ

8X+7X=405

15X=405

X=405/15

X=27

THEN

8X =8x27 =216

7X=7x27=189

Answer 2

Answer:

The two numbers are 216 and 189

Given:

Sum of two numbers = 405

Ratios the numbers = 8 : 7

Step-by-step explanation:

In accordance with the ratio of the numbers,

Let the two numbers be "8a" and "7a"

According to the Question,

8a + 7a = 405

→ 15a = 405

→ a = 405/15

⇒ a = 27

So,

8a = 8 × 27 = 216

7a = 7 × 27 = 189

∴ The two numbers are 216 and 189
