The lowest common denominator (LCM) is the lowest whole number divisible by both denominators without a remainder.
EASY LCM:
multiply the two denominators, then divide the total by the greatest common factor (GCF) between the two denominators.
=(64*32)/32
=2,048/32
=64
-OR-
DETAILED METHOD
STEP 1:
Find prime factors of denominators.
8/64
64: 2 x 2 x 2 x 2 x 2 x 2
8/32
32: 2 x 2 x 2 x 2 x 2
STEP 2:
If factors occur more than once, multiply them the greater number of times they occur.
2 x 2 x 2 x 2 x 2 x 2= 64
ANSWER: The LCM of 8/64 and 8/32 is 64.

Answer:
You add by +4.
Step-by-step explanation:
-5 + 4 = -1
-1 + 4 = 3
3 + 4 = 7
7 + 4 = 11
11 + 4 = 15
and then you just add on with +4.
If you are still confused, make sure to use a number line.
Answer: 9a-9b-6
7(3a−2b)+5b−3(4a+2)
Distribute:
7(3a−2b)+5b−3(4a+2)
=(7)(3a)+(7)(−2b)+5b+(−3)(4a)+(−3)(2)
=21a+−14b+5b+−12a+−6
Combine Like Terms:
=21a+−14b+5b+−12a+−6
=(21a+−12a)+(−14b+5b)+(−6)
=9a+−9b+−6
