<h3>What are fractions?</h3>
A fraction is a non-integer. It is made up of numerators and denominators. An example of a fraction is 2/3. 2 is the numerator and 3 is the denominator.
<h3>What are four common denominators for the fractions?</h3>
The common denominators for the fractions are numbers that would divide both 2 and 3. This numbers can be determined by multiplying 2 and 3 and finding the multiple of the product.
2 x 3 = 6

Answer: 2970
Step-by-step explanation:
First, you do the first exponent in the first part which is 10^3 and the answer for that is 1000. Then you do 2.4x1000 which is 2400. Afterwards you do the second part's exponent which is 10^2 and you get 100 for that. Next, you do 5.7x100 which is 570. Finally you add 2400+570 and get 2970.
For both of them you just make them into fraction.
For #2

and then you simplify it
36. ÷12 3
-----. =. --------
120. ÷12 10
After this you want to change the fraction to a percentage.Percentage are out of 100
so you simply will multiply by 10 to the top and bottom
3. 30
----. * 10 =. -----. = 30%
10. 100
The answer is 30%
For number #3
you simply put 63 over 240
63
-----
240



21
----
80
is that answer because it can't be simplified
after that
Answer:
76
Step-by-step explanation:
The median line in the middle of the box is at 76 (the number line is by 2's)
Divide the pages read by the portion read:
60/ 3/4 = 60 x 4/3 = 240/3 = 80
