"Simplifying a complex fraction" means Simplifying a complex fraction means to rewrite the fractions in the numerator and in the denominator with common denominators.
Step-by-step explanation:
A complex fraction is one where either the numerator or the denominator or both contains common a fraction.
There are two methods to simplify a complex fraction-
First Method
- We simplify the numerator until we have one single fraction.
- Then we simplify the denominator until we have one single fraction.
then we divide by multiplying the numerator by the reciprocal of the denominator.
- The end result is simplified
Second Method
- Firstly we find a common denominator of all the fractions in the numerator and all the fractions in the denominator .
- Then we multiply the number in the numerator and denominator of the complex fraction by a common denominator found in step 1.
- The result is simplified
Answer:
4(-14z + 7)
Step-by-step explanation:
This expression is equivalent because if you distribute the 4 into the parenthesis, the same expression of -56z + 28 will be formed.
To find other expressions, find a common factor between the two numbers. For instance, a number that could replace the four outside of the parenthesis is 7; 56 divided by 7 is 8 and 28 divided by 7 is 4.
Hope this helps!
