Question

Write the following using numbers, literals and signs of a basic operations :
One-fourth of $x$ multiplied by twice the sum of $y$ and $z$.

Answer 1

One-fourth of $x=\frac{x}{4}$

Twice the sum of $y$ and $z=2(y+z)$

Now,

One-fourth of $x$ multiplied by twice the sum of $y$ and $z=\frac{x}{4}\times 2(y+z)=\frac{x(y+z)}{2}$
