We have a question: A museum has eight different wings displaying four times as many artifacts as paintings displayed. Three of the wings are dedicated to paintings. The artifacts are divided evenly among the remaining wings. One painting is so large it takes up an entire wing, and the other two wings house 12 smaller paintings each. How many artifacts are in each artifact wing?
And an answer: 20
So how you got the answer?
The museum has 2 * 12 + 1 = 25 paintings displayed in the painting wings. There are 4 times as many artifacts displayed, so there are 25 * 4 = 100 artifacts. There are 8 wings and 3 are painting wings, so there are 8 - 3 = 5 artifact wings. Each artifact wing has 100 / 5 = 20 artifacts in it.

We have a question: Erica is getting dessert at a pie buffet where all the pies are the same size. She takes 1/5 of an apple pie and 3/4 of a cherry pie. What fraction of a whole pie did Erica take, expressed as a percentage?
And an answer: 95
So how you got the answer?
First, find a common denominator for the fractions by multiplying 5 and 4: 5 * 4 = 20. Then convert 1 / 5 to twentieths by multiplying the top and bottom by 4: 1 / 5 * 4 / 4 = 4 / 20. Then convert 3 / 4 to twentieths by multiplying the top and bottom by 5: 3 / 4 * 5 / 5 = 15 / 20. Now that the two fractions have the same denominator, you can add them: 4 / 20 + 15 / 20 = 19 / 20. Now divide 19 by 20 and multiply the answer by 100 to convert the fraction to a percentage: 19 / 20 * 100 = %95.

We have a question: John buys a heating pad for $30. He uses it 3 times a week for 2 weeks. How much does he spend on each use?
And an answer: 5
So how you got the answer?
He uses it 3 * 2 = 6 times. So he pays 30 / 6 = $5.
