Question

Joshua was experimenting with a division problem 0.72 / 0.8 and noticed that he could create another division problem with the same quote to select all the division problems that have the same quotient

Answer 1

$\frac{0.72}{0.8}=\frac{0.72}{0.8}\cdot\frac{100}{100}=\frac{0.72\cdot100}{0.8\cdot100}=\frac{72}{80}$$\frac{0.72}{0.8}=\frac{0.72}{0.8}\cdot\frac{10}{10}=\frac{7.2}{8}$$\frac{0.72}{0.8}=\frac{\frac{0.72}{10}}{\frac{0.8}{10}}=\frac{0.072}{0.08}$

Then, choices 2 and 4 are correct
