Question

what is that number one third of which added to 5 gives 8

Answer 1

1/3x + 5 =8 1/3x = 8-5 1/3x=3 x=3*3 x= 9.

Answer 2

Given - Sum

Find - Number

Solution - Let the number be x.

So, 1/3 of the number = 1/3*x

Now, addition of 5 gives 8. The equation that will form is -

1/3*x + 5 = 8

Solving the equation for the value of x.

Performing multiplication to find the value of x

$\frac{x}{3} + 5 = 8$

Performing substraction to find the value of x

$\frac{x}{3} = 8 - 5$

$\frac{x}{3} = 3$

Performing multiplication to find the value of x

$x = 3 \times 3$

$x = 9$

So, 1/3 of 9 when added with 5 gives 8.
