To determine the number of sandwiches you can make, you need to divide the total mass of ham and bread by the combined mass of ham and bread in one sandwich.
1. Calculate the total mass of ham and bread:
- Mass of ham = 1kg = 1000 grams
- Mass of bread = 1kg = 1000 grams
2. Calculate the combined mass of ham and bread in one sandwich:
- Mass of ham = 7 grams
- Mass of bread (2 slices) = 25 grams + 25 grams = 50 grams
3. Divide the total mass of ham and bread by the combined mass in one sandwich:
- Number of sandwiches = (Total mass of ham + Total mass of bread) / (Mass of ham + Mass of bread) in one sandwich
- Number of sandwiches = (1000 grams + 1000 grams) / (7 grams + 50 grams)
- Number of sandwiches = 2000 grams / 57 grams (rounded to the nearest whole number)
The number of sandwiches you can make is approximately 35.
To calculate the mass of the sandwiches made, multiply the number of sandwiches by the combined mass of ham and bread in one sandwich:
- Mass of sandwiches = Number of sandwiches x (Mass of ham + Mass of bread) in one sandwich
- Mass of sandwiches = 35 sandwiches x (7 grams + 50 grams)
- Mass of sandwiches = 35 sandwiches x 57 grams
The mass of the sandwiches made is approximately 1995 grams.
To calculate the mass of the ingredients left over, subtract the mass of the sandwiches made from the total mass of ham and bread:
- Mass of ingredients left over = (Total mass of ham + Total mass of bread) - Mass of sandwiches made
- Mass of ingredients left over = (1000 grams + 1000 grams) - 1995 grams
The mass of the ingredients left over is approximately 5 grams.
