Chapter 1 FraCtions 35

We will ease into the topic of word problems by translating English sen-
tences into mathematical sentences. We will not solve word problems until later
in the book.

EXAMPLES

•   Five is two more than three.

5 = 2 + 3

· 12 = 6

•   Eggs cost $1.15 per dozen.

1.15 / 12 (this gives the price per egg)

•   The difference of sixteen and five is eleven.

16 − 5 = 11

•   Fourteen decreased by six is eight.

14 − 6 = 8

•   Seven increased by six is thirteen.

7 + 6 = 13

•   Eight is less than eleven.

8 < 11

•   Eight is at most eleven.

8 ≤ 11

•   Eleven is more than eight.

11 > 8

•   Eleven is at least eight.

11 ≥ 8

•   One hundred is twice fifty.

100 = 2 · 50

•   Five more than eight is thirteen.

5 + 8 = 1 3
