Write the word sentence as an inequality. A number k is less than 10.

Answer 1

For writing inequalities, the most important part is knowing which sign to use. A trick I teach students is that you want the open part of the inequality pointing to the bigger value. So in this example you would have k<10, the "open" part of the sign is toward the bigger number. I hope this makes sense.

Answer 2

k<10

less than <

greater than >

less than or equal to <=

greater than or equal to >=

got it?
