Question

Solve: $z+2=4\frac{1}{5}$

Answer 1

Step 1: Converting mixed fraction into improper fraction
Given equation : $z+2=4\frac{1}{5}$

$z+2=\frac{5\times 4+1}{5}$

$z+2=\frac{20+1}{5}=\frac{21}{5}$

Step 2: Finding the value of $z$

$z+2-2=\frac{21}{5}-\frac{2}{1}$

$z=\frac{21-(5\times 2)}{5}$

$z=\frac{21-10}{5}=\frac{11}{5}$

$z=2\frac{1}{5}$

Hence, the value of $z$ is $2\frac{1}{5}$
