Answer:
0.5 Inches per hour
Step-by-step explanation:
Most normal people won't know exactly what unit rate is, or how to calculate it. So I'm here to help!
This is a fraction equal to
6 inches ÷ 12 hours
We want a unit rate where
1 is in the denominator,
so we divide top and bottom by 12
6 inches ÷ 12
12 hours ÷ 12
=
0.5 inches
1 hour
=
0.5 inches
hour
= 0.5 inches per hour
Glad I was able to help!
Answer: It's 48%. See below.
Step-by-step explanation:
By definition, percent means out of a hundred. For instance, 10 percent is 10 out of 100.
One way to make 
a percent is by making the denominator 100. In order to do so, multiply the numerator and the denominator by 4, since 25 times 4 is 100.
= 
= 48 %
This is very simple, and mental math is definitely possible. Hope this help.
=2 4/5
8/10+2
2+8/10=2 8/10
4/5- -2/1
(4x1)-(-2x5) divided by 5x1
=4- -10 divided by 5
=14/5
=2 4/5
Answer:
2 1/6
Step-by-step explanation:
Because the denominators are different, and there are whole numbers involved, then first make the fractions improper.
4 1/2 -> 9/2
6 2/3 -> 20/3
Next, make the denominators the same by multiplying each fraction by the denominator of the other.
9/2 * 3 = 27/6
20/3 * 2 = 40/6
Then you can subtract the numerators because the denominators are the same:
40/6-27/6= 13/6
Then you can convert to a mixed fraction if need be.
