Question

If Steady uses $\frac{7}{10}$ of dark chocolate and $\frac{2}{10}$ of white chocolate to bake a pie, how much chocolate does he use in all?

• A. $\frac{8}{10}$
• B. $\frac{9}{10}$
• C. $\frac{5}{10}$
• D. $\frac{6}{10}$

Answer 1

The correct option is B $\frac{9}{10}$


The denominators are the same, we add the numerators.
Steady uses $\frac{7}{10}$+$\frac{2}{10}$=$\frac{7+2}{10}$=$\frac{9}{10}$.
