2 x 2 x 2 x 3
Because you are multiplying two, four times
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 = 
Answer:
= 0.857143 miles per hour
Step-by-step explanation:
This the fractions 3/4 miles and 7/8 hours are equal to
0.75 miles and 0.875 hours
We want a unit rate where
1 is in the denominator,
so we divide top and bottom by 0.875
<u>0.75 miles</u> ÷ 0.875
0.875 hours ÷ 0.875
=
<u>0.857143 miles</u>
1 hour
so the answer would be...
= 0.857143 miles per hour
It's the third one and the last one are the only ones that make immediate sense.
