Question

Add.
4 5/8 + 2 1/4 =?

Answer 1

6 7/8

Explanation:

Take a quick look at those fractions. The LCD here is 8. We'll leave 4 5/8 as is, but change 2 1/4 to 2 2/8.

Now we'll add together:

4 5/8

+ 2 2/8

-----------

6 7/8

Answer 2

`6 (7)/(8).`

The easiest way to solve this problem is to sum the whole number and the fractions separately.

`4(5)/(8) + 2(1)/(4)\\\\4(5)/(8) + 2 (1)/(4)((2)/(2))\\\\4(5)/(8) + 2(2)/(8)`

Solving the sum:

`4(5)/(8) + 2(2)/(8) = 6 (7)/(8)`
