The phrase is less 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.
k < 10
Practice makes perfect
We are given a word sentence and we want to write an inequality that it represents.
A number k is less than 10.
Every inequality has an inequality symbol and values or expressions on either side of this symbol. In this exercise, we have the phrase is less than, so we can identify that the inequality symbol should be <.
Anumberk < 10.
On the left-hand side, we have the phrase a number k. These words tell us that k is a variable symbol.
Anumberk < 10.
k < 10
On the right-hand side, we have the constant 10. If we put these sides together, we have a complete inequality.
A number k is less than 10.
k < 10
