1 * 7 + 2 * 1 + 3 * 3 + 4 * 2 + 5 * 2 =
7 + 2 + 9 + 8 + 10 =
36
Now we need to divide 36 by the total frequency: 7+1+3+2+2=15
36 / 15 = 2.4
140 divided by 14 is your base, which is 10 square meters.
To answer the question above, evaluate the number of cookies each of them placed on a tray. The calculations are shown below,
Ronny C1 = 0.15 x 20 = 3
Celina C2 = 3
Jack C3 = 0.30 x 20 = 6
Michelle C4 = 20 - (3 + 3 + 6) = 8
From the calculation above, <em>Michelle</em> placed the most number of brownies on the tray.
4/5 + 8/9. First we have to find a common denominator for
and
.
Now we are going to add:
Make
a mixed number:
So the answer is
You can find the unit rate when given a rate by setting up a proportion of the rate equal to how many per one.
40 miles per 2 hours = 20 miles per one hour.
20 miles/hour is a unit rate. (How many per one?)
