What is 4 3/4 + 2 1/2

7 1/4

Step-by-step explanation:

Multiply the denominator of 1/2 to equal the denominator of 3/4.

3/4 + 2/4 = 1 1/4.

4 + 2 = 6.

6 + 1 1/4 = 7 1/4.

convert it to improper fractions first

4 3/4

multiply the whole number by the denominator

4*4 = 16

then add the numerator

16+3 = 19

so 4 3/4 = 19/4

apply the same concept to 2 1/2 to get 5/2

now add them

19/4 + 5/2

common denominator = 4

multipky the second fraction’s numerator and denominator  by 2

5*2 = 10

2*2 = 4

5/2 = 10/4

now add

19/4 + 10/4 = 29/4

which you can convert back to a mixed fraction by dividing to the nearest whole number

4*7 = 28

which leaves 1/4

29/4 = 4 1/4

easy math just plug in a and b
