9x/9=45/9

So, 4.5=20

5.5=25

will be sum to 45

Answer 2

Answer :

• The numbers are 20 and 25

Given :

• Two numbers in ratio 4 : 5
• Sum is 45

To find :

• The numbers

Solution :

Given, the two numbers in ratio 4 : 5 so,

• Let the two numbers be 4x and 5x

Sum is 45

According to question

➞ 4x + 5x = 45

➞ 9x = 45

➞ x = 45/9

➞ x = 5

Finding the numbers :

➞ 4x

➞ 4(5)

➞ 20

➞ 5x

➞ 5(5)

➞ 25

Hence,The numbers are 20 and 25

Verification :

➞ 4x + 5x = 45

➞ 4(5) + 5(5) = 45

➞ 20 + 25 = 45

➞ 45 = 45

Hence , Verified
