The smith family drinks 1 4/5 liters of apple juice each day. the apple juice comes in a 2 liter bottle. How many bottles does mrs. smith need to buy every week?
1 4/5 = 9/5
2/(9/5) * 7
and round up to a whole bottle
To find out how many bottles Mrs. Smith needs to buy every week, we need to calculate the total amount of apple juice the Smith family drinks in a week and then divide it by the capacity of each bottle.
First, let's find out how much apple juice the Smith family drinks in one day. They drink 1 4/5 liters of apple juice each day, which is equivalent to 1.8 liters (since 4/5 = 4 divided by 5, which is 0.8).
Now, we need to calculate the total amount of apple juice consumed in a week. Since there are 7 days in a week, we multiply the daily consumption by 7: 1.8 liters x 7 days = 12.6 liters.
Next, we divide the total amount of apple juice consumed in a week (12.6 liters) by the capacity of each bottle (2 liters) to find out the number of bottles required. 12.6 liters / 2 liters = 6.3 bottles.
Since we can't have a fraction of a bottle, we round up to the next whole number. Therefore, Mrs. Smith needs to buy 7 bottles of apple juice every week to ensure an adequate supply for the family.
