Jax's Maths Goal

Hi, I have some hard maths goals.

They are
1. Grouping within 1000
2. Converting fractions to decimals
3. Memorising factors.

 An example of grouping within 1000 is 367 + ? = 1000. That equals 633.

An example of converting fractions to decimals is 1/3 = ?%. That equals 33.33333333333333 recurring.

And finally, factors.The factors of 36 are 1,2,3,4,6,9 and 12.
