2 answers:
Answer:
A. =
Step-by-step explanation:
of the students wore shorts.
of the students wore jeans.
Converting the fractions of the students who wore shorts and jeans respectively;
= 0.25
= 0.25
This means that the ratio of students who wore shorts is the same as that of students who wore jeans.
i.e =
Answer:
A.
Step-by-step explanation:
This is a case of equivalent fractions which means that the fractions represent the same amount.
Why are they the same? Because when you multiply or divide the same number up and down simultaneously, the fraction maintains its value. The rule to remember is:
What you do to the top of the fraction
you also have to do it to the bottom part!
Therefore, these fractions are actually the same:

The answer is:
The missing step is the step shown in the last option:
D.
To find which is the missing step, we need to remember that to cancel a square root, we need to elevate it, so:
Starting from the last step before the missing step, we have:
In order to calculate the value of the variable (x) we need to square both sides of the equation, since squaring a root will cancel the root.
We must remember the following properties:
Now, finding the missing step, we need to find what to do in order to get the expression of the following step.
So, squaring both sides of the equation in order to cancel the square root and isolate the variable, we have:
Hence, we found the the missing step is:
D.
Have a nice day!
