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

Sagot :

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

[tex]\begin{gathered} \frac{a}{b}\frac{\cdot}{\cdot}\frac{c}{d}=\frac{a\cdot d}{b\cdot c} \\ b,d\ne0 \end{gathered}[/tex]

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

[tex]\frac{1}{3}\frac{\cdot}{\cdot}\frac{3}{5}=\frac{1\cdot5}{3\cdot3}=\frac{5}{9}[/tex]

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