Question

Express 17.28 as a mixed number.

Answer 1

Since 0.28 extends to the hundredths place, your mixed number starts off as 17 28/100.
Simplify 28/100 to 7/25.
Now, your mixed number is 17 7/25.

Answer 2

17.28
= 17+ 0.28
= 17+ 28/100
= 17+ (28/4) / (100/4)
= 17+ 7/25
= 17 7/25

The final answer is 17 7/25~
