Krishna

Krishna bought 5 1/2 meters of ribbon from the market. She cut off a 2 3/4 m piece of ribbon from it and gave it to Sushma. What length of ribbon is left with her?

Correct answer:

x =  2 ³⁄₄ = 11/4 m

Step-by-step explanation:

$$\begin{gathered} K=5\frac{1}{2}=5+\frac{1}{2}=\frac{5\cdot 2+1}{2}=\frac{10+1}{2}=\frac{11}{2}=5.5\text{m} \\ S=2\frac{3}{4}=2+\frac{3}{4}=\frac{2\cdot 4+3}{4}=\frac{8+3}{4}=\frac{11}{4}=2.75\text{m} \\ x=K-S=\frac{11}{2}-\frac{11}{4}=\frac{22}{4}-\frac{11}{4}=\frac{22-11}{4}=\frac{11}{4}=\frac{11}{4}\text{m}=2\frac{3}{4}\text{m}=2.75\text{m} \end{gathered}$$
