Answer 1

Answer:

This is a simple question that can be answered quickly using basic mathematical principles. We first need to convert the mixed fractions into improper fractions.

3 1/2 = [(2×3)+1]/2 = 7/2

8 1/4 = [(4×8)+1]/4 = 33/4

Let's call the number to be added 'x.' So the equation for the question will be

7/2 + x = 33/4

We can solve this by basic rules of linear equations and subtraction of fractions.

x = 33/4 - 7/2

x = (33 - 14)/4…….(the LCM of 2 and 4 is 4)

x = 19/4

Now, we can convert the improper fraction of x into a mixed fraction.

19 = 4×4+3……..(since the denominator is 4)

x = 4 3/4
