The ribbon

Maricel has 12 ⅝ meters of ribbon. She gave 5 ⅛ meters to Annalise and 4 ⅜ meters to Analisa. How many meters of ribbon was left to her?

Correct answer:

x =  3 ¹⁄₈ = 25/8 m

Step-by-step explanation:

$$\begin{gathered} M=12\frac{5}{8}=12+\frac{5}{8}=\frac{12\cdot 8+5}{8}=\frac{96+5}{8}=\frac{101}{8}=12.625\text{m} \\ A=5\frac{1}{8}=5+\frac{1}{8}=\frac{5\cdot 8+1}{8}=\frac{40+1}{8}=\frac{41}{8}=5.125\text{m} \\ B=4\frac{3}{8}=4+\frac{3}{8}=\frac{4\cdot 8+3}{8}=\frac{32+3}{8}=\frac{35}{8}=4.375\text{m} \\ x=M-A-B=\frac{101}{8}-\frac{41}{8}-\frac{35}{8}=\frac{101-41-35}{8}=\frac{25}{8}=\frac{25}{8}\text{m}=3\frac{1}{8}\text{m}=3.125\text{m} \end{gathered}$$
