Answer:

Step-by-step explanation:
First, use distribution to simplify

Then, simplify further by combining like terms

Solve


÷

First, apply the rule (easiest way if you have learned it):

÷

×


×
Second, apply the last rule:

×

Third, multiply 5 × 10 to get 50.
Fourth, multiply 6 × 9 to get 54.
Fifth, find the GCF of 50 and 54.
The GCF should be 2.
Sixth, divide the numerator by the GCF.

÷
Seventh, divide the denominator by the GCF.

÷
Eighth, now put 25 and 27 together to get the simplified fraction.
