seven tenths of a number is less than 8.4 find all possible values of the number

Answer 1

Let the number be x.

We are given that 7/10 of the number is less than 8.4.

So we can write the inequality as:

(7/10)x < 8.4

Multiplying both sides by 10 to get rid of the fraction:

7x < 84

Dividing both sides by 7:

x < 12

Therefore, all possible values of the number are x < 12.
