Answer 2

Calculation of Remaining Rice Bags

To calculate the number of rice bags remaining, we need to subtract the number of bags used from the total number of bags delivered.

Given: - 5 bags of rice were delivered to the cafeteria. - 1 1/8 bags were used on the first day. - 2 3/8 bags were used on the second day.

To find the number of bags remaining, we subtract the bags used from the total bags delivered:

Total bags delivered: 5 bags Bags used on the first day: 1 1/8 bags Bags used on the second day: 2 3/8 bags

To convert the fractions to a common denominator, we can multiply the numerator and denominator of each fraction by 8:

Bags used on the first day: 9/8 bags Bags used on the second day: 19/8 bags

Now we can subtract the bags used from the total bags delivered:

Total bags delivered: 5 bags Bags used on the first day: 9/8 bags Bags used on the second day: 19/8 bags

Remaining bags = Total bags delivered - Bags used on the first day - Bags used on the second day

Remaining bags = 5 - 9/8 - 19/8

To subtract fractions, we need to have a common denominator. In this case, the common denominator is 8:

Remaining bags = (40/8) - (9/8) - (19/8)

Now we can subtract the numerators:

Remaining bags = (40 - 9 - 19)/8

Simplifying the numerator:

Remaining bags = 12/8

Simplifying the fraction:

Remaining bags = 3/2

Therefore, there are 3/2 bags of rice remaining in the cafeteria.

Please note that it is not possible to have half a bag of rice, so the remaining bags should be rounded up to the nearest whole number. In this case, there is 1 bag of rice remaining.
