Thank you

Hi

how to solve 5 3/4+ 1 2/3 in two different ways

What are you supposed to solve ? (there is no sign, no unknown...)

Its in form of a fraction so its
3 2
5-- + 1---
4 3

They want the answer to be expressed as a mixed number.

The OP meant simplify.

In this case....



Simplifies to:





LCD is 12







Another way to do this is to find the LCD when they are mixed numbers, and then simplify them to normal fractions.

5 3/4 + 1 2/3 = (5 + 1) + (3/4 + 2/3) = 6 + (9/12 + 8/12) = 6 + 17/12 = 7 + 5/12 = 7 5/12.
