The orange arrow is adding up to 0.90 and the blue arrow is subtracting 1.30 so the answer is (-0.40)
Answer:
C
Step-by-step explanation:
total number of wheels=4*21=84
Write the fractions in ascending order: 1/4, 2/8 (same as 1/4), 3/4 and 4/8 (same as 1/2). 3/4 is greater than 1/4, greater than 2/8 and greater than 4/8, so Audrey, at 4/8, at the most.
