Question

A box of wooden sticks weighs $\frac{15}{45}$ kg, and a box of nuts weighs $\frac{21}{45}$ kg. Find the total weight of 4 such 15 boxes of wooden sticks and one such box of nuts.

• A. $\frac{7}{45}$ kg
• B. $\frac{81}{45}$ kg
• C. $\frac{82}{45}$ kg
• D. $\frac{60}{45}$ kg

Answer 1

The correct option is B $\frac{81}{45}$ kg

Let’s solve the problem stepwise.

● Weight of 1 box of wooden stick $=\frac{15}{45}$ kg

● To find the weight of 4 such boxes, we will add $\frac{15}{45}$ four times.

● $\frac{15}{45}+\frac{15}{45}+\frac{15}{45}+\frac{15}{45}=\frac{15+15+15+15}{45}=\frac{60}{45}$ kg

● Weight of 1 box of nuts $=\frac{21}{45}kg$

● Total weight = Weight of 4 boxes of wooden sticks + Weight of a box of nuts

● Total weight $=\frac{60}{45}kg+\frac{21}{45}kg=\frac{81}{45}kg$

Thus, A is the correct option.
