There are two things here you need to understand.

1: What is a mixed number - it is a mixture of a whole number and a fraction.

2: Understand which part is which in 2.7

2 is the whole number 0.7 is the fraction.

What is 0.7 as a fraction? It is 7/10

So 2.7 as a mixed number is 2 and 7/10

I hope this helps
