How to get the answer, Step-by-Step
1) Multiply by cross-over.
Multiply the first fractions' denominator (3) by the second fractions' numerator, (1). Do it the other way around, and add the two numbers together. Adding them gives you a total of 10.
2) Find the denominator.
If you still don't know how to find it, multiply both of the fractions' denominators, [(3)x(7)], giving you a total of 21.
3) Put it into one fraction.
Place the 10 as the numerator, and 21, as the denominator. That is usually it, but you asked for it simplified. Let me explain.
4) Simplify.
You have to find their least common multiple, also known abbreviated, LCM.
10 and 21 both share only one number- 1. It cannot be simplified. Or in another way, what number can you both divide it by?
Ex. 6 and 4 both share 2. 6 can be divided by 2, and 4 can also be divided by 4.
Finale Answer?
Is, 10/21.
