Question

A restaurant ordered 3 bags of flour. Each bag weighs 4 2/5 kg. The restaurant used 2 1/4 kg of flour and spilled 1/8 kg. How much flour was left? Express answer in kilograms and grams.

Answer 1

3 bags of flour = 4 2/5 kg x 3 = 12 6/5 kg

Total flour used = 2 1/4 kg + 1/8 kg = 2 5/8 kg

Remaining flour = 12 6/5 kg - 2 5/8 kg = 10 1/8 kg

10 1/8 kg = 10 kg + 825 g

Answer: 10 kg and 825 g

Answer 2

A bag weighs 4 2/5 = 4.4 kg.
The restaurant used in total 2 1/4 + 1/8 = 2.375 kg.
The total amount of flour the restaurant ordered is 13.2 kg.
Therefore, the restaurant is left with 13.2 - 2.375 = 10.825 kg of flour.
In grams, 10.825 kg is equal to 10,825 grams.
So the answer is 10 kg 825 grams.

Answer 3

Again, apologies for the confusion earlier.

Let's go through the calculation step by step with the correction:

1. First, let's convert the bag weight from mixed fraction to decimal form.
A bag of flour weighs 4 2/5 kg, which is:
4 + (2/5) kg
= 4 + 0.4 kg
= 4.4 kg

2. The restaurant ordered 3 bags.
Total weight of flour = 3 bags × 4.4 kg/bag
= 13.2 kg

3. Next, let's convert the total flour used from mixed number and fractions to decimals.
The total flour used is 2 1/4 kg and 1/8 kg.

Convert 2 1/4 to decimal:
2 1/4 = 2 + (1/4)
= 2 + 0.25
= 2.25 kg

Convert 1/8 to decimal:
1/8 = 0.125 kg

Now add both amounts of used and spilled flour:
Total flour used = 2.25 kg + 0.125 kg
= 2.375 kg

4. Now, calculate the remaining flour.
Remaining flour = Total weight of flour - Total flour used
= 13.2 kg - 2.375 kg
= 10.825 kg

Let's convert 10.825 kg to kg and grams.

5. There are 1000 grams in a kilogram, so:
0.825 kg = 0.825 × 1000 grams
= 825 grams

So, the restaurant is left with 10 kg and 825 grams of flour.

Your final answer is correct. The restaurant has 10 kg 825 grams of flour remaining.
