On both the SAT and ACT, it’s important to know how to translate words into math. Make sure you read all word problems carefully. I often tell my students that every section on the SAT and ACT is a reading section.
When you run into the following phrases on a test, be prepared to translate them into math! Here are some helpful hints:
Translating Words into Algebra
ADDITION: increased by, more than, combined, together, total of, sum, plus, added to
SUBTRACTION: decreased by, minus, less, difference between, difference of, less than, fewer than
MULTIPLICATION: of, times, multipled by, product of, by a factor of
DIVISION: per, out of, ratio of, quotient of, percent (divide by 100)
EQUATION: is, are, was, were, will be, gives, yields, sold for
Let’s look at some examples.
Twenty-eight is what percent of two hundred?
28 = (x/100) * 200
How much greater is the product of thirty-three and twenty-four than the sum of eleven and eight?
(33 * 24) - (11+8)
If the ratio of tables to chairs in the office is three to two, how many chairs are in an office with nine tables?
3/2 = 9/x
The length of a room is forty more feet than its width. What is the area of the room in terms of its width?
Mike has x books, which is three times the amount of Joe but only a third the amount of Sue. How many books do Joe and Sue have together?
x/3 + 3x
