What is 2/5 plus 1/3

1 answer:

First, you need to get the denominators (the bottom number) the same. The smallest number to get them to is 15.

So, what you need to do is take 2/5 and multiply the bottom by 3 to get 15, and since you did it to the bottom, you need to do it to the top too. So you would get, 6/15.

Then, for 1/3, take the bottom number and multiply it by 5. Then, since you did it to the bottom, do it to the top as well. You would get 5/15.

Then, you need to put them side by side. You don't add the bottom, so your denominator would remain 15, but your numerator (top) would get added.

<u> 6</u> + <u>5</u> = <u>11</u>
15 15 15

How do you represent selling 6 copies as an integer? How do you represent receiving 24 books as an integer?

Sholpan [36]

Answer:

How do you represent selling 6 copies as an integer? With -6

How do you represent receiving 24 books as an integer? With 24.

Step-by-step explanation:

The important thing to state here is what is the thing that you are counting.

If you count the number of copies/books that you have, then:

Selling 6 copies means that you have 6 copies less than before, then you would represent this with a -6.

"-6 copies"

And receiving 24 books means that you have 24 books more than before, then you will represent this with a +24.

"24 books"

(You do not need to write the "+" sign, it is implicit if you don't write any sign)
