Answer:
1 7/10
Step-by-step explanation:
2 1/10 - 3 4/5= 1 7/10 but if you don't understand this then...
Take the wholes and minus both of them which makes 1 (BTW this will be your whole number) Then convert 4/5 into tenths (easier way: draw 4 circles and cut them in half, then count all the halves. That will be your answer, in this case my answer would be 8/10) Now since Shane spent 2 1/10 hours on track we are going to take the fraction beside the whole number (AKA 1/10) and minus it by our 4/5 (AKA 8/10) Now we have 7/10. Our answer would be 1 7/10.
