NEED HELP ASAP!!!

If a five on a dice is rolled 10 times within 50 rolls, how many times would you roll a five if you rolled the dice 300 times?

Answer 1

60

Explanation:

There are two ways to check that I know.

First way:

Double 50, 10 automatically doubles too.

50x2=100

10x2=20

Then we can multiply the 100 by to equal 300, the 20 also automatically multiplies to equal 60.

100x3=300

20x3=60

Second way:

10 is 20% of 50 we can find that bu multiplying 20% and 50, like this:

20%x50= 10

To find out the answer if the 5 was changed to a 300 we would have to multiply 20% of 300.

20%x300= 60

We've looked at two ways to solve this problem and both ways equal 60. So, therefore, the answer for this question is 60.

Answer 2

10/50 = x/300
3000 = 50x
60 = x
