Answer and explanation:
Cable tv cost changed by $67-$55= $12= 12/55×100=21.818%
Cable TV cost increased by 21.818% of original cost
Dozen of eggs cost changed by $2.19-$1.79= $0.4= 0.4/1.79×100= 22.636%
Dozen of eggs cost increased by 22.636% of original cost
Therefore both customers can't be correct, cost of a dozen of eggs increased the most.
The answer would be >, because 7.63 is greater than 7.629. :)
Answer: 9/14
Step-by-step explanation:
As Eric ran 5/7 of the distance ran on Friday, you have to times 5/7 by the distance ran on Friday.
So we have:
5/7 x 9/10 = 9/14
This is calculated by multiplying the numerators (numbers on top) and the denominators (numbers on the bottom)
Numerators:
5x9 = 45
Denominators:
7x10 = 70
So we now have the new fraction: 45/70, if we simplify this, we get:
45/70 = 9/14
(dividing the top and bottom both by 5)
