Two numbers are in the ratio 5ratio7 if the sum of the numbers is 720,find the numbers
Answers
a:b
5:7
lets keep that in mind.
the first step in finding the values in such questions is to add shares. this means we will add 5+7, which equals 12.
we are sure that the number in whole is getting divided on only a and b, so we will divide this number over the total shares.
720/12, it equals 60. now what we just got is a single share. whats left to do?
5:7. first we will find a. 5(total number of shares in a)*60( value of one share)
=300. so we now have 300:b
now we'll find b. 7(total number of shares in b)*60( value of one share)
=420.
this is the simplest way to solve such questions and word problems.

Given that:
- Two numbers are in the ratio 5 : 7.
- The sum of the numbers is 720.
To Find:
- The certain numbers.
Let us assume:
- The certain numbers be 5x and 7x respectively.
Finding the certain numbers:
According to the question.
ㅤ↠ㅤ5x + 7x = 720
ㅤ↠ㅤ12x = 720
ㅤ↠ㅤx = 720/12
ㅤ↠ㅤx = 60
Hence,
- First number = 5x = 5(60) = 300
- Second number = 7x = 7(60) = 420
