When adding fractions, you have to make sure the bottom numbers are the same. Otherwise, you can't add them.

So currently, the bottom number for the first fraction is 5. The bottom number for the second fraction is 2.

As you can see, 5 is not the same as 2, so we need to find one number to make sure the bottom number is the same for both the fractions.

You can multiply the the first fraction by 2, and the second fraction by 5 to give you two fractions that have the same denominator (bottom number.)

So, 3/5 multiplied by 2 is the same as multiplying 3 by 2, and 5 by 2. That gives you 6/10.

1/2 multiplied by 5 is 1 multiplied by 5, and 2 multiplied by 5, which is 5/10.

Now that you have your converted fractions, you can add them and forget about the bottom number, as it's the same. When adding fractions, if the bottom numbers are equal, you leave it as it is, so the 10 stays as 10:

6/10 + 5/10 = 11/10 

Notice how I added 6 and 5 to give me 11, but I don't add 10 + 10, because I don't need to.

So the answer is 11/10.

Find the volume of the figures.A. 907.5 cmB. 126ncmC. 605 cmD. 55 cm
-BARSIC- [3]

We have the next formula to calculate the volume

V=\frac{1}{3}\cdot a^2\cdot h

where a is the length of the side in the base and h is the height

a=11cm

h=15cm

we substitue the values in the formula

V=\frac{1}{3}\cdot11^2\cdot15=605\operatorname{cm}^3
