Question

The weight of 10 identical samples of a substance is 0.01 pound what is the weight of 10,000 samples

Answer 1

We use ratios here.

For every 10 samples, the total weight is 0.01 lb.

We write
10 / 0.01.

We want to find the weight of 10,000 samples.

We write
10,000/?

These two ratios must equal each other.

(10 / 0.01) = (10,000 / ?)

If you know how to cross-multiply, then we can do that here.
0.01 * 10000 = 10 * ?
100 = 10 * ?

The unknown value is 10, which is your answer.

Answer 2

The weight of 10,000 samples is:

10 pounds.

Explanation:

It is given that:

The weight of 10 identical samples of a substance is 0.01 pound.

i.e. 10 samples= 0.01 pound.

Now we are asked to find the weight of 10,000 samples.

Since,

10 samples= 0.01 pound.

1000×10 samples= 1000×0.01 pounds

i.e.

10000 samples= 10 pounds.

Hence, the answer is: 10 pounds.
