Multiply the two fractions: 1/5 * 2/3

When multiplying fractions it is important to note the following steps: 1) Simplify the fractions if not in lowest terms. 2) Multiply the numerators of the fractions to get the new numerator. 3) Multiply the denominators of the fractions to get the new denominator. When applying these steps to the example pair of fractions, our answer will come down to "2/15".

Where __________ you live when you were a child? a) did b) have c) were d) do

This question is an example of learning how to use the correct grammatical term in accordance with proper tense. The correct answer would be "did" as it is in tense agreement with the word "were", which implies a past tense. If we were to use process of elimination as another strategy we can easily see that none of the other answer options make any grammatical sense.

There are b boys in the class. This is three more than four times the number of girls. How many girls are in the class?

Let x represent the unknown number that you are asked to find: Let x be the number of girls. (Although b is not known, it is not what you are asked to find.) The problem states that "This" -- b -- is three more than four times x: 4x + 3 = b. Therefore, 4x = b − 3 x = (b − 3)/4 The solution here is not a number, because it will depend on the value of b. This is a type of "literal" equation, which is very common in algebra.
