Answer:
12
Step-by-step explanation:
You need to find the least common denominator (LCD) to all the denominators of the fractions present in the equation. These denominators are (writing them in their prime factor form to make our calculations easier):
Therefore, we need to include a factor of 3, and two factors of 2 (
) in our least common denominator, so this LCD will be a perfectly divided by all three given denominators, therefore eliminating all fractions in the equation.
Our LCD is = 
PEMDAS. parenthesis, exponents, multiple or divide (whichever come first from left to right), add or subtract (whichever comes first from left to right)
So first do stuff in parenthesis.
Then do divide because thats next on the list and it happens earlier than the multiply one.
So, A
7/10 - 1/4 use common denominators
28/40 - 10/40 = 18/40 = 9/20
Answer:
see explanation below
Step-by-step explanation:
1500 × 3 × 20 ÷ 100
$900
Its 75 because you at the 2 variables and then subtract them by 180 so 180-105=75
