Question

the sum of the rational number 5/16 and 7/12​

Answer 1

Answer:

5/16+7/12

15+28/48

43/48

Answer 2

Step-by-step explanation:

That would be the same as 7/12 - 5/16 which is 13/48

To subtract fractions just make the denominators the same.

In this case the lowest common denominator is calculated as follows:

12 = 3*4 = 3*2*2

16 = 4*4 = 2*2*2*2

The lowest common denominator then is 2^4 * 3 = 16*3 = 48

So 7/12 = 28/48

and 5/16 = 15/48

so 7/12 - 5/16 = 28/48 - 15/48 = (28–15)/48 = 13/48.

Hope this helps
