Answer:
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.
