    Perfect. I think you got the hang of this now, and I doubt GCSE would often ask you to turn repeating decimals into fractions.
    Thanks.

    What can I move on to now?

    I'm not sure, it's up to you, whatever topics you're not comfortable with, perhaps.

    What exactly is a decimal? People try to tell me but I never get a good answer.

    A fraction whose numerator is expressed by the figures of tenths, hundreths, thousandths... (basically everything to the right of a decimal point) while the denominator is some power of 10.

    So what isn't a decimal number then?

    Integers. Where the denominator is 100 = 1. Can be negative powers too if you wish but generally no need to count those.

    Looks good! Don't forget to convert them into fractions when you're done with decimals.

    First one is wrong, but the third one is right. 1 and 0.01 cannot both be equal to 1/100, can they?

    Second one is right as well as the fourth one. You can get rid off the 0 in front of the 5 there. Also look for ways to simplify the fractions; like the fourth one can go into 1/20 as both 5 and 100 are divisible by 5.

    For 5 you multiplied the numerator by 100 but the denominator by 1000? Pick one or the other; can't do both
