Question 288403
Notice how {{{2100/30=70}}}. Stated another way, {{{70*30=2100}}}


Since 30 milliliters = 1 ounce, we can multiply both sides by 70 to get: 2100 milliliters = 70 ounces




So now we're dealing with 70 ounces. The problem now is that 8 does not go into 70, but we can note that {{{70/8=8.75}}} or {{{8*8.75=70}}}. So multiply both sides of 8 ounces = 1 cup by 8.75 to get: 70 ounces = 8.75 cups


Since 70 ounces = 8.75 cups and 2100 milliliters = 70 ounces, we now know that 2100 milliliters = 8.75 cups



So over the course of 7 hours, the patient will drink 8.75 cups of fluid. Simply divide this result by 7 to find the amount of fluid the patient will drink in one hour. So {{{8.75/7=1.25}}}



Since {{{1/4=0.25}}}, this means that {{{1.25=1&1/4}}}. So the patient will drink {{{1&1/4}}} cups of fluid over the course of one hour.
