Question

Steve has two 1 L oil jars. Jar 1 contains $\frac{3}{7}$ parts of oil and jar 2 contain $\frac{2}{7}$ parts of oil. What fraction of oil does Steve have?

• A. $\frac{5}{7}$
• B. $\frac{4}{7}$
• C. $\frac{6}{7}$
• D. $\frac{6}{7}$

Answer 1

The correct option is A $\frac{5}{7}$

$\text{The fraction of oil in Jar 1}=\frac{3}{7}$

$\text{The fraction of oil in Jar 2}=\frac{2}{7}$

Total fraction of oil with Steve = Oil in Jar 1 + Oil in Jar 2
$=\frac{3}{7}+\frac{2}{7}$

$=\frac{3+2}{7}$

$=\frac{5}{7}$




$\text{Therefore, the total fraction of oil with Steve}$
$is\frac{5}{7}.$
