students were asked to choose their favorite subject. if $\frac{3}{10}$ of the students chose history and $\frac{5}{10}$ chose biology, what fraction chose either history or biology?

Explanation:

Step1: Identify the operation

We need to add the fractions.
$\frac{3}{10}+\frac{5}{10}$

Step2: Add the numerators

Since the denominators are the same, we add the numerators.
$\frac{3 + 5}{10}=\frac{8}{10}$

Step3: Simplify the fraction

Divide both numerator and denominator by 2.
$\frac{8\div2}{10\div2}=\frac{4}{5}$

Answer:

$\frac{4}{5}$
