Answer:
20) 2.084 meters
21) $75
22) 0.123 meters
23) 4 foot pieces
Explanation:
20) divide the length by 4:
8.336 ÷ 4 = 2.084 meters
21) divide total cost by the amount of tickets:
39300 ÷ 524 = $75
22) subtract the smaller number from the greater number:
0.884 - 0.761 = 0.123 meters
23) the greatest common factor of 8 and 12 is 4, so he should cut each rope into 4 foot long pieces
