Han used 1 1/3 gallons of paint to paints 4/7 of a shed. How many gallons of paint will it take to a paint the whole shed. Write a multiplication equation or a division equation to represent this situation, then find the answer. Show your reasoning.

Answer :

Given that Han used this amount of paint:

[tex]1\frac{1}{3}gal[/tex]

to paint this part of a shed:

[tex]\frac{4}{7}[/tex]

You can convert the Mixed Number to an Improper Fraction as follows:

1. Multiply the whole number part by the denominator of the fraction.

2. Add the Product to the numerator.

3. The denominator does not change.

Then:

[tex]1\frac{1}{3}=\frac{(1\cdot3)+1}{3}=\frac{4}{3}[/tex]

Let be "x" the number of gallons of paint that it will take to paint the whole shed.

You can set up the following equation to represent the situation:

[tex]\frac{4}{7}x=\frac{4}{3}[/tex]

Now you need to solve for "x" in order to find its value:

1. Apply the Multiplication Property of Equality by multiplying both sides of the equation by 7:

[tex]\begin{gathered} (7)(\frac{4}{7}x)=(\frac{4}{3})(7) \\ \\ 4x=\frac{28}{3} \end{gathered}[/tex]

2. Apply the Division Property of Equality by dividing both sides of the equation by 4:

[tex]\begin{gathered} \frac{4x}{4}=\frac{28}{3\cdot4} \\ \\ x=\frac{28}{12} \\ \\ x=\frac{7}{3} \end{gathered}[/tex]

Hence, the answer is:

- Equation:

[tex]\frac{4}{7}x=\frac{4}{3}[/tex]

- Solution:

[tex]x=\frac{7}{3}[/tex]
