Writing decimals as fractions

To convert a decimal to a fraction, we write the decimal number as a numerator and we write its place value as the denominator.
If there is a number to the left of the decimal point, we keep that number as a whole number.
Example 1: 0.07
0.07 is 7 hundredths. So, we write 7 over 100.
Example 1: 2.1
2.1 is 2 and 1 tenth. 2 stays a whole number. Then we write 1 over 10.
