Answer:
a summary is an average and an average is mean
Step-by-step explanation:
to get the mean add all the cakes sold together then divide by number of years
21+28+19+26+21=115
115/5=23
so....
first one: mean
second one: 23
Unit fractions are fractions with a 1 as the numerator(number on top)
so 3/8 equals 1/8+1/8+1/8
8
3/4
x/32
Solve for x, = 24
Subtract 24 from 32
Also another way
4 x n = 32
n = 8
3x8 = 24
Subtract and same result
The answer is in the red part but the work is everything on top.
