The width 2

The width of stamp M is 4/3 inches, and the length is 7/5 inches. The dimensions of stamp M are 7/6 times the dimensions of stamp P. What is the length of stamp P in inches?

Correct answer:

L₂ =  1.2 in

Step-by-step explanation:

$$\begin{gathered} W_1=4/3=\frac{4}{3}\doteq 1.3333\text{in} \\ {L}_1=7/5=\frac{7}{5}=1.4\text{in} \\ M=\frac{7}{6}\cdot P \\ P=\frac{6}{7}\cdot M \\ {W}_2=\frac{6}{7}\cdot W_1=\frac{6}{7}\cdot \frac{4}{3}=\frac{6\cdot 4}{7\cdot 3}=\frac{24}{21}=\frac{8}{7}\doteq 1.1429\text{in} \\ {L}_2=\frac{6}{7}\cdot L_1=\frac{6}{7}\cdot \frac{7}{5}=\frac{6\cdot 7}{7\cdot 5}=\frac{42}{35}=\frac{6}{5}\text{in}=1.2\text{in} \end{gathered}$$
