Answer 1

Answer:

If two numbers are 4x and 5x

then,4x+5x=180

9x=180

x=180÷9

x=20

two numbers are 4x=4×20=80

5x=5×20=100

Answer 2

Given:

• Two numbers are in the ratio of 4:5
• Sum of those numbers is 180

To find:

• Number?

Solution:

Given that two numbers are in ratio of 4:5

Let suppose that constant of ratio is x.

Therefore,

• Numbers will be 4x and 5x

Now, given that sum of numbers is 180.

Therefore,

4x + 5x = 180

→ 9x = 180

→ x = 180/9

→ x = 20

Therefore, number are as :

• 1st number = 4x => 4×20 = 80
• 2nd number = 5x => 5×20 = 100
