Question

$\frac{4}{5}+\frac{2}{8}=$
a $\frac{16}{5}$
b $\frac{5}{16}$
c $\frac{1}{5}$
d $\frac{1}{16}$

Explanation:

Step1: Simplify the fraction

Simplify \(\frac{2}{8}\) to \(\frac{1}{4}\). So the expression becomes \(\frac{4}{5}+\frac{1}{4}\).

Step2: Find a common denominator

The common denominator of \(5\) and \(4\) is \(20\). Rewrite the fractions: \(\frac{4\times4}{5\times4}=\frac{16}{20}\) and \(\frac{1\times5}{4\times5}=\frac{5}{20}\).

Step3: Add the fractions

\(\frac{16}{20}+\frac{5}{20}=\frac{16 + 5}{20}=\frac{21}{20}\). Wait, no, there is a mistake. Wait, original problem is \(\frac{4}{5}\div\frac{2}{8}\).

Step1: (Correct operation)

When dividing by a fraction, multiply by its reciprocal. So \(\frac{4}{5}\div\frac{2}{8}=\frac{4}{5}\times\frac{8}{2}\).

Step2: Simplify the multiplication

\(\frac{4\times8}{5\times2}=\frac{32}{10}=\frac{16}{5}\).

Answer:

A. \(\frac{16}{5}\)
