All the angles have to equal 180. If you add the two angles you get 140. You take 180 and subtract 140 and it equals to 40. The missing angle is 40 degrees.

Darren bought some paint. He used 2 1/4 gallons painting his living room. After that, he had 3 5/6 gallons left. How much paint
Otrada [13]

Answer: 6\frac{1}{12}\ gallons

Step-by-step explanation:

We can make the conversion from mixed numbers to improper fractions:

  • Multiply the whole number part by the denominator of the fraction.
  • Add the numerator of the fraction and the product obtained (This sum will be the new numerator).
  • The denominator is the same.

Then:

2\frac{1}{4}=\frac{(2*4)+1}{4}=\frac{9}{4}\\\\3\frac{5}{6}=\frac{(6*3)+5}{6}=\frac{23}{6}

We need to add the fractions in order to calculate the amount of paint Darren bought. Since the denominators are differente, we must find the Least Common Denominator (LCD):

4=2*2=2^2\\\\6=2*3\\\\\\LCD=2^2*3=12

Then:

\frac{9}{4}+\frac{23}{6}=\frac{27+46}{12}=\frac{73}{12}\ gallons

To convert this improper fraction to a mixed number:

  • When you divide 73 by 12 you get a quotient of 6. This will be the whole number.
  • The remainder obtained is 1. This will be the numerator of the fraction.
  • The denominator does not change.

Then:

\frac{73}{12}\ gallons=6\frac{1}{12}\ gallons
