Question

divide 108 in two parts in the ratio 4:5

Answer 1

hey,
it very simple:

Let the parts be x.
= 4x,5x
then ,
4x +5x=108
9x=108
x=108/9
x=12

which shows the two parts will be 4x=4*12=48
5x=5*12=60.

hope it will help

Answer 2

Given:

The number = 108

Ratio = 4:5

To Find:

Division of 108 in two parts

Solution:

Let the parts be = x.

Thus, 4:5, it will be 4x and 5x

Now, as per question -  

4x +5x = 108

9x = 108

x = 108/9

x = 12

Substituting the value of x in two given parts -  

=  4x

= 4 × 12

= 48

= 5x

= 5 × 12

= 60

Answer: The number when divided as per 4:5 is 48 and 60.
