Answer:
129:175
Explanation:
Andy and Christopher are measuring a liquid solution using a graduated cylinder
Andy uses 3.5 liters of the liquid solution
3.5 liters to mililiters
= 3.5 ×1000
= 3500 mililiters
Christopher uses 2580 mililiters
Therefore the ratio of Christopher's measurement to Andy's measurement can be calculated as follows
= 2580/3500
= 129 : 175
Hence the ratio of Christopher's measurement to Andy's measurement is 129:175
