The number of times the tires will have to spin is 24.9 times. How I got this was by finding the circumference, the equation in this case where pi is 3.14 is 3.14(2.1). That equals 6.594, then you divide 164 by 6.594 to get 24.87109 blah blah and you round that up to 24.9.
Answer:
I believe the answer is C. hope this helps
1a. Split the larger piece(1/3) into half to show the two pieces
1b. Both are 3/6 or 1/2
2a. It shows 1/2 +1/4
2b.cut it so there are 3 1/4 pieces, so cut the 1/2 piece horizontally in the middle
2c. 2/4 + 1/4 = 3/4. 1/2 + 1/4 = 3/4
