1/4 of the students have a B, so there are 12 people in the class so what you would do is divide 12 by 4 and get an answer of 3 so 3 people got a B
Answer:
Step-by-step explanation:
Im sure this means add because on a number line when you move to the right its adding. And since the amount of units were moving up by is 6 we would add 0+6 which equals 6.
For example, if x/2=7, x would be equal to 7x2=14, bringing the whole number the variable is divided by to the other side of the equation.
