Question
Write the following using literals, numbers and signs of basic operations:
One-third of x multiplied by the sum of a and b.

Answer

One-third of x is $\frac{\text{x}}{3}.$
The sum of a and b is (a + b)
$\therefore$ One third of x multiplied by the sum of a and b
$=\frac{\text{x}}{3}\times(\text{a + b})=\frac{\text{x}(\text{a + b})}{3}$
