Question

It takes Violet 3/5 hour to paint a chair. How much of the chair will be finished after 1/3 hour? Choose the model that correctly illustrates the problem 1/3 ÷ 3/5

Answer 1

We have the following rule for the division of fractions:'

`\begin{gathered} (a)/(b)(\cdot)/(\cdot)(c)/(d)=(a\cdot d)/(b\cdot c) \\ b,d\\e0 \end{gathered}`

then, in this case, we have to divide 1/3 by 3/5 to find out how much of the chair will be finished:

`(1)/(3)(\cdot)/(\cdot)(3)/(5)=(1\cdot5)/(3\cdot3)=(5)/(9)`

thus, after 1/3 hour, only 5/9 of the chair will be finished
