Feedback: Not quite! Convert $\frac{3}{5}$ into a decimal (0.6) and add 0.4 + 0.6 = 1

Feedback: Not quite! Convert $\frac{3}{4}$ into a decimal (0.75). Subtract 0.6 from 0.75, giving 0.15.

Feedback: Not quite! Convert $\frac{4}{5}$ to 0.8, then add: $0.875 + 0.8 = 1.675$.

Feedback: Not quite! Convert $ \frac{1}{2} $ to $ 0.5 $ and add $ 0.3 + 0.5 = 0.8 $. Then, convert $ 0.8 $ to a fraction: $ 0.8 = \frac{8}{10} $, which simplifies to $ \frac{4}{5} $.

Feedback: Not quite! Convert $0.5$ to $\frac{1}{2}$ and find the common denominator (14). Subtract $\frac{7}{14} - \frac{4}{14} = \frac{3}{14}$.

Feedback: Not quite! Convert 0.3 to a fraction ($\frac{3}{10}$). Rewrite $\frac{3}{10}$ as $\frac{18}{60}$ and $\frac{5}{12}$ as $\frac{25}{60}$. Add $\frac{18}{60} + \frac{25}{60} = \frac{43}{60}$.
