Firstly, you will change the decimal into a fraction and then change it into a mixed number. That's the way I learnt it.
1550 is an integer and cannot be expressed as a mixed number. As a decimal, it is 1550 - exactly as in the question.
You can write a fraction that is a mixed number as a decimal by diving the numerator by the denominator then rounding it to the nearest thousand.
u can write it as a mixed number or a whole number
put the number behind the decimal over 100 nad reduce it.
Keep the whole-number-part exactly as it is, and re-write the decimal part as a fraction.
1.71 as a mixed number in simplest form = 171/100
Fraction: 219/20 Mixed number: 10 and 19/20
10.9 is a decimal which can also be written as 10 and 9/10
