2.8 = 2 + 0.8
*let's analyze the decimal 0.8 as a fraction
0.8 = 8/10
*but if we divide the numerator and denominator by the same common factor of 2, we find that the fraction can be reduced to:
(8/2)/(10/2) = (4)/(5) = 4/5
*now evaluating the whole value of 2 (from the 2.8), we know there are a total of (5) - fifths in order to make a whole, so for 2 whole, we require:
2*(5/5) = (2*5)/5 = 10/5
*Now we add the fractions together:
2 = 10/5
0.8 = 4/5
10/5 + 4/5
*add numerators only, the denominator stays as a 5
(10 + 4)/5 = 14/5
*there are no common factors between 14 & 5 (other than 1, but that won't help reduce the fraction any), so the fraction is in it's simplest form:
answer is: 14/5

Answer:
The First table is going by 6 on the top, the bottom is going by 1.5.
<u> 6 12 18 24</u>
1.5 3 4.5 6
The Second table is going by multiplying by 2 on the top, the bottom is doing the same thing(from least to greatest).
<u>112.8 56.4 28.2 14.1 </u>
5,640 2,820 1,140 570
The cost per pound of apples on sale is $1.50.
3÷2= 1.50
You can buy 12 pounds of apples for $18.00.
18.00÷1.5= 12
Since 1 pound=16 ounces, so there are about 3 apples in each pound.
16÷5= 3.2
You can buy approximately 36 apples with $18.00.
12×3= 36
