Julian

Julian picks 1 ⅗ kg fewer blueberries in the morning than in the afternoon. If Julian picked 3 ⅛ kg in the morning, How many kilograms of blueberries does he pick in the afternoon?

Final Answer:

b =  4 ²⁹⁄₄₀ = 189/40 kg

Step-by-step explanation:

$$\begin{gathered} a=3\frac{1}{8}=3+\frac{1}{8}=\frac{3\cdot 8+1}{8}=\frac{24+1}{8}=\frac{25}{8}=3.125\text{kg} \\ b=a+1\frac{3}{5}=\frac{25}{8}+1\frac{3}{5}=\frac{25}{8}+\frac{8}{5}=\frac{125}{40}+\frac{64}{40}=\frac{125+64}{40}=\frac{189}{40}=\frac{189}{40}\text{kg}=4\frac{29}{40}\text{kg}=4.725\text{kg} \end{gathered}$$
