Answer:
No
Step-by-step explanation:
It is not necessary to have a common denominator when multiplying fractions. To multiply fractions with different denominators, you multiply the numerators with each other and then the denominators with each other. The end product of multiplying fractions with no common denominator may not be in its lowest terms however, and might need to be reduced. For example, if you were to multiply 1/2 by 2/3, you would first multiply the numerators (1 and 2) to get 2, and then the denominators (2 and 3) for a product of 2/6. After getting this product, reduce it to its lowest terms, end up with 1/2 by dividing both the numerator and denominator by 2, and end up with 1/3 as a final product. Thus, it is not necessary to have common denominators when multiplying fractions.

All we have to do is divide the money she spent on fruit by the total and multiply that by 100.
18÷45
.4×100
40
So, Carmen spent 40% of her money on fruit.
Answer:
h(x) = 3(x - 5)^2 + 6.
Step-by-step explanation:
g(x) = 3x^2 + 8
Shifting 5 units to the right gives:
3(x - 5)^2 + 8
Now 2 units down :
3(x - 5)^2 + 8 - 2
= 3(x - 5)^2 + 6.
Answer:
8,566,379,470 people
Step-by-step explanation:
Let's start simple. In order to find the population increase on January 1, 2006, we need to multiply 6,486,915,022 by 1.4% and add it to 6,486,915,022.
- 6,486,915,022*1.4% = 90,816,810.308
- 90,816,810.308+6,486,915,022 = 6,577,731,832.31 people on January 2006.
Note that the above two steps gives the same answer as 6,486,915,022*1.014.
So we need to do this for each year. 20 years pass between 1/1/2005 and 1/1/2025.
We need to do 6,486,915,022*1.014*1.014*1.014... 20 times.
This is equivalent to 
.
Multiplying it out gives us 8566379470.2 = 8,566,379,470 people.
