Answer 1

Answer:

$30\div2=15$

Explanation:

We want to divide 30 by 2;

$30\text{ }\div2$

solving we have;

$\begin{gathered} 2\lvert30\rvert\Rightarrow15 \\ 2\text{ in 3 = 1 remainder 1} \\ \text{ since we are left with 1, we will then have 2 in 10, which is equal to 5.} \\ \text{ Altogether;} \\ 30\div2=15 \\ \frac{30}{2}=\frac{20}{2}+\frac{10}{2}=10+5=15 \end{gathered}$

Therefore;

$30\div2=15$
