Answer:
3rd one, 4th one, and last one.
Step-by-step explanation:
3rd one - multiplying the numerator (10) by 4.5 would give you 45. Same thing with the denominator
Same thing with the 4th and last one.
4th - Multiplying the numerator and denominator by 45 would give you the other fraction
Last one - Multiplying the numerator and denominator by 4 would give you the other fraction
