if x erasers have a weight of 80 grams, what is the total weight of 50 erasers?
(50/x)*80
To find the total weight of 50 erasers, we need to determine the weight of one eraser and then multiply that by the total number of erasers.
Given that x erasers have a weight of 80 grams, we can set up a proportion to find the weight of one eraser:
x erasers = 80 grams
1 eraser = (80 grams) / x erasers
Now we can find the weight of one eraser:
1 eraser = (80 grams) / x erasers
Since we are given that there are 50 erasers, we can substitute this value for x and find the weight of one eraser:
1 eraser = (80 grams) / 50
1 eraser = 1.6 grams
Now that we know the weight of one eraser, we can calculate the total weight of 50 erasers:
Total weight of 50 erasers = (Weight of one eraser) * (Number of erasers)
Total weight of 50 erasers = 1.6 grams * 50
Total weight of 50 erasers = 80 grams
Therefore, the total weight of 50 erasers is 80 grams.
