if x erasers have a weight of 80 grams, what is the total weight of 50 erasers?
50x * 80
and then what do you do to solve the problem??
To find the total weight of 50 erasers, we can use a concept called proportion.
Given that x erasers have a weight of 80 grams, we need to determine the weight of 50 erasers. Here's how we can set up the proportion:
x erasers = 80 grams
50 erasers = ?
To solve this proportion, we can create a ratio:
(x erasers) / (80 grams) = (50 erasers) / ( ? grams)
To find the value of "? grams", we will cross-multiply and solve for it:
(x erasers)( ? grams) = (80 grams)(50 erasers)
Now, let's solve for "? grams":
(x erasers)( ? grams) = (80 grams)(50 erasers)
Cross-multiplying, we get:
(x erasers)( ? grams) = 4000 grams•erasers
Now, divide both sides of the equation by "x erasers" to isolate "? grams" on one side:
? grams = (4000 grams•erasers) / (x erasers)
Since we know that x erasers have a weight of 80 grams, we can substitute this value into the equation:
? grams = (4000 grams•erasers) / (80 grams)
Simplifying the equation gives us:
? grams = 50 grams
Therefore, the total weight of 50 erasers is 50 grams.
