Question

Separate 72 into 2 parts, one of which shall be 1/3 of the other

Answer 1

The second part of 72 is
`((215)/(3))`

Explanation:

The whole part is given as = 72

One part of it = 1/3

Let the other part of it = k

Now,according to the question:

First Part + Second Part = 72

or,
`k +  ((1)/(3))   = 72`

⇒
`k   = 72  -   ((1)/(3))`

or,
`k   =   ((216 -1)/(3))  \implies k = (215)/(3)`

or, k = 215/3

Hence, the second part of 72 is
`((215)/(3))`
