To make the sum or difference of 3/4+1/3

Mathematics

Answer:

13/12 or 1 1/12

Step-by-step explanation:

First, I like to line up the fractions like this:

3/4

1/3

You can't add them yet because they have different denominators, so we have to get them to the same denominator first. What is a number 3 and 4 can be multiplied by? Let's use 12. So, we want both of their denominators to be 12. How do we do that? 4 times what equals 12? 3. However, whatever you multiply the denominator by, you have to do to the numerator as well. Here is what we have:

3/4 x 3

1/3

3x3 equals 9, so your first fraction is 9/12. Then, do the second fraction. 3 times what equals 12? 4. So, multiply the numerator, 1, by 4 to get 4. So, your second fraction is 4/12. Now, you have to add them together, 9+4 = 13. The denominator stays the same. So, your sum is 13/12. If you want to, you can also simplify it to a mixed number into 1 1/12.

Alex73 [517]

Not sure which ratio you need, but 6/9 = 2/3

Step-by-step explanation:

$39 = 2lb salmon and 3lb swordfish

1lb salmon=$6           6+6 = 12

1lb swordfish=$9       9+9+9 = 27

12+27 = 39
