Ok so say u have 3 2/4. 3 is ur whole number, 2 is ur numerator, and 4 is ur denominator. First:
2
3 —
4
U multiply 3 and 4 and get 12, now keep 12 in ur head, there is no need to write it down, unless u want too...now u add 12+2 (2 is the numerator) which is 14. So ur whole number and numerator are now gone but ur denominator stays, it’s still 4, and now that ur old numerator is gone u replace it with 14 so u get 14/4. And there is ur improper fraction
