what is the difference between multiplying fractions and adding/subtracting fractions? complete sentances please

Answer:

See Explanation!

Step-by-step explanation:

When multiplying fractions, you do not need a common denominator, and the entire fraction gets multiplied across, however when adding or subtracting fractions, you must have a common denominator, and then only compute the numerator, as the bases are already the same

Solve 3(x - 2) < 18
vladimir2022 [97]

Hi there!

\large\boxed{x < 8}

3(x - 2) < 18

Begin by dividing both sides by 3:

3(x - 2)/3 < 18/3

x - 2 < 6

Add 2 to both sides:

x - 2 + 2 < 6 + 2

x < 8
