Form algebraic expression in the following case using variables, constants, and arithmetic operator $(+, -, \times, \div)$
One-fourth of the sum of numbers $a a n d b$

Open in App

Solution

Sum of numbers $a a n d b = a + b$
Now, one-fourth of the sum of the numbers $a a n d b = \frac{1}{4} o f (a + b)$
$= \frac{1}{4} \times (a + b)$ ( $∵$ of means mutiplication)
Hence, the required algebraic expression is $\frac{1}{4} \times (a + b)$
