Write each decimal as a fraction 0.64=

0.64

this has to do with place valuewhat place value is ur last digit (6) in ? It is in the hundredths place. so we put the 64 (without the decimal) over 100.
64/100 which reduces to 16/25. Its that simple.

Examples :
0.5the last digit (5) is in the tenths place...so put it over 10.
5/10 reduces to 1/2.

0.225...the last digit (5) is in the thousandths place. 225/1000 reduces to
9/40

The answer would be 7 cages
