Work out the answer to the following as simple fractions and explanation

Simple fractions require basic math. Since you are multiplying fractions, follow the basic steps in order to get the answer (simplified or not).

Step 1:

Simplify the fractions if not in lowest terms. 
For example in the given equation, since it is in its lowest term, we opt to leave it as it is.

Step 2:

Multiply the numerators of the fraction in the given equation to get a niew numerator

9 x 2 = 18

Step 3:

This is the same as step 2. Multiply the denominators in the given equation to get a new denominator

10 x 5= 50

Step 4:

Simplify the resulting fraction if possible

9/10 x 2/5 = 18 / 50

The answer 18/50 can be simplified and the resulting fraction will be 9/25

Byou start by adding them all and setting them equal to 180 since that is half of the total degrees in a circle.(2x+8) + (3x-14) + (3x-14) = 1808x-20 = 1808x = 200x = 25
