<span>In
the fairest school 20% are below 16 years old
1/3 are teachers which is equals to = 21
Let’s start solving:
=> 1/3 of 100% = ( 100 / 3 = 33.33% )
thus 33.33% = 21
=> 21 x 3 = 63, is the total number of people in the school.
Let’s try solving the number of people below 16 years old
Then there are 20% of it:
=> 63 * .20 = 12.6
Thus, there are around 13 people who are 16 years old younger.</span>
Answer:
Place "SUM" at 4 on the number line.
Step-by-step explanation:
8 + (-4) = 8 - 4 = 4
Adding a negative number is the same as subtracting its opposite. Adding -4 is the same as subtracting 4.
21 divided by 3 = 7
That means the brother is 14 years younger.
36 - 14 = 22
The brother will be 22 years old.
