Step-by-step explanation:

as the other answer did correctly :

when dividing by a fraction, this is the same as multiplying with the upside-down fraction.

so,

-3/2 / 7/4 or -3/2 ÷ 7/4 (both symbols mean the same) is the same as

-3/2 × 4/7

and multiplying fractions is easy (the top parts are multiplied and create the result top part, and the bottom parts are multiplied and create the result bottom part).

so, the result is

(-3×4) / (2×7) = -12/14 = -6/7

Quantity of paint left = \frac{389}{480} gallons

Solution:

Quantity of yellow paint = 1\frac{1}{5}=\frac{6}{5} gallons

Quantity of green paint = 1\frac{1}{6}=\frac{7}{6} gallons

Quantity of blue paint = \frac{7}{8} gallons

Quantity of paint used = \frac{3}{4} gallons of each paint

Quantity of paint left = 1-\frac{3}{4}=\frac{1}{4} gallons of each paint

Quantity of paint left = (\frac{6}{5}+\frac{7}{6}+\frac{7}{8})\times\frac{1}{4}

Taking LCM for 5, 6, 8, we get LCM = 120

(\frac{6}{5}+\frac{7}{6}+\frac{7}{8})\times\frac{1}{4}=(\frac{144}{120}+\frac{140}{120}+\frac{105}{120})\times\frac{1}{4}

                         =(\frac{389}{120})\times\frac{1}{4}

                         =\frac{389}{480}

Hence, Mark will have \frac{389}{480} gallons of paint left after painting the mural.
