The phrase is fewer than divides the sentence into what should be on the left-hand side and what should be on the right-hand side of the inequality.
2p < 7
Practice makes perfect
We are given a word sentence and we want to write an inequality that it represents.
Twice a number p is fewer than 7.
Every inequality has an inequality symbol and values or expressions on either side of this symbol. In this exercise, we have the phrase is fewer than, so we can identify that the inequality symbol should be <.
Twicea numberp < 7.
On the left-hand side, we have the phrase Twice a number p. These words tell us that p is a variable symbol and that the operation that will be used in our inequality is the multiplication. This is because of the word Twice.
Twice a numberp < 7.
2* p < 7
On the right-hand side, we have the constant 7. If we put these sides together, we have a complete inequality.
Twice a number p is fewer than 7.
2* p < 7
