Question

Express 105/20 as a mixed number in simplest form.

Answer 1

the integer part of $\frac{105}{20} = 5$
5*20=100
105-100=5
The mixed number in simplest form of 105/20 = 5$\frac{5}{20}$ = 

5$\frac{1}{4}$

Answer 2

we know that

A mixed number is a number consisting of a whole number and a proper fraction.

so

we know that

$\frac{105}{20}=5.25\\ \\\frac{105}{20}=5+0.25\\ \\\frac{105}{20}=5+\frac{25}{100} \\ \\\frac{105}{20}=5+ \frac{1}{4}\\ \\\frac{105}{20}=5\frac{1}{4}$

therefore

the answer is

$5\frac{1}{4}$
