"Interconversion of Fractions and Decimals" The meaning and properties of fractions PPT courseware 2

1. Fill in the blanks:

(1) 0.9 means ( ) divided by ( ).

(2) 0.07 means ( ) divided by ( ).

(3) 0.013 means ( ) divided by ( ).

(4) 4.27 means ( ) and ( ) divided into ( ).

To convert a fraction into a decimal, just write a few 0s after the 1 as the denominator, and remove the decimal point as the numerator; after converting it into a fraction, you can reduce the fraction to a fraction.

If the denominator is 10, 100, 1000, etc., you can directly remove the denominator and see how many zeros there are after 1 in the denominator. Then count the number to the left from the last digit in the numerator and click on the decimal point.

If the denominator is not 10, 100, 1000... to convert a decimal into a fraction, the denominator must be used to remove the numerator; if it cannot be divided, you can keep as many decimals as necessary by rounding.
