I am 15 years old so please I need help solving this math problem; I asked a lot of people and they advice me to put my question here, so I don't know whether this is really the right place.

I have 5-digits number:

75421
I want to calculate:

1- the higher multiplication result

2- the higher division result

3- the less multiplication result

4- the less division result

the constraints are making two numbers from the former number, the first one consisting of two digits, the other consisting of 3 digits,

for example 75*421 74*521

Thank you in advance.

2 and 4 are easy. 754/12 and 12/754. Multiplication requires a little work: the digits in each term must be in descending order for largest and ascending order for smallest.
