Question

If n erasers have a weight of 80 grams, what is the total weight of 50 erasers?

Answer 1

Answer:

$The\ weight\ of\ the\ 50\ erasers\ be\ \frac{4000}{n}\ grams.$

Step-by-step explanation:

As given

if n erasers have a weight of 80 grams .

I.e

n erasera =  80 grams.

1 erasers weight .

$1\ erasers\ weight = \frac{80}{n}$

Now find out the weight of the 50 erasers.

$Weight\ of\ 50\ erasers = \frac{50\times 80}{n}\ grams$

Simplify the above

$Weight\ of\ 50\ erasers = \frac{4000}{n}\ grams$

$Therefore\ the\ weight\ of\ the\ 50\ erasers\ be\ \frac{4000}{n}\ grams.$

Answer 2

Answer:

weight of 50 erasers is $\frac{80}{n}\times 50$  g

Step-by-step explanation:

Given that n erasers have a weight of 80 grams,

we have to find total weight of 50 erasers

Now, weight of n erasers=80 g

∴ weight of 1 eraser = $\frac{80}{n}$ g

⇒  weight of 50 erasers =  $\frac{80}{n}\times 50$  g

Hence, weight of 50 erasers is  $\frac{80}{n}\times 50$  g
