Answer:

part a: 3 6/8

Step-by-step explanation:

part a: you have to find the difference between them. if you find something like this again what I would do is do how many whole numbers there are between the two number in this case 3. then figure out what the fraction is. the fraction isn't how many spaces there are in-between but how many there are counting the final number. so from 12 to 13 there are 7 spaces plus the number 13. then you figure it out from there.

Part A
Heaviest - lightest = difference
15-12=3
