Calculating Fractions and Decimals

Feedback: Not quite! First, add the decimals: $0.5 + 0.4 = 0.9$. Then, add the fractions: $\frac{2}{5} + \frac{1}{5} = \frac{3}{5} = 0.6$. Finally, $0.9 + 0.6 = 1.5$.

Feedback: Not quite! First, add the fractions: $\frac{4}{7} + \frac{3}{7} = 1$. Then, add the decimals: $1.2 + 0.3 = 1.5$. Finally, $1 + 1.5 = 2.5$.

Feedback: Not quite! First, simplify the fractions: $\frac{5}{6} - \frac{1}{3} = \frac{5-2}{6} = \frac{1}{2} = 0.5$. Then add: $2.3 + 0.5 = 2.8$.

Feedback: Not quite! First, subtract the fractions: $\frac{5}{8} - \frac{1}{8} = \frac{4}{8} = 0.5$. Then, calculate the decimals: $2.4 - 1.1 = 1.3$. Finally, $1.3 + 0.5 = 1.8$.

Feedback: Not quite! Using the distributive law: $6 \times \frac{5}{6} = 5$, and $6 \times 0.2 = 1.2$. Then subtract: $5 - 1.2 = 3.8$.

Feedback: Not quite! Factor out $\frac{5}{6}$: $\frac{5}{6} \times (3.6 - 1.8 + 0.2). Combine the terms in the brackets: $3.6 - 1.8 + 0.2 = 2$. Finally, $\frac{5}{6} \times 2 = \frac{5}{3}$.
