Question

0.02 as a fraction I have problems with decimals

Answer 1

1/50
Because first you do the 0.02 = 2/100
It's over 100 because of the amount of digits.
Then simplify 2/100. Half of 2 is 1 and half of 100 is 50.
Sorry if that didn't really help, but i wanted to try. 

Answer 2

0.02, so it will be under 100 because you have 2 numbers after the ' . ' (0 and 2)

$0.02= \frac{2}{100} ^{/2}= \frac{1}{50}$
