Equivalent Ratios. Students learn to find equal ratios by first writing the given ratio as a fraction, then multiplying the numerator and denominator of the fraction by the same number. For example, to find two ratios that are equal to 1:7, first write 1:7 as the fraction 1/7. I hope this helps
Answer: 5/6
Step-by-step explanation:
First find total number of soccer balls.
1 + 1 + 4 = 6
4 + 1 = 5 non-blue soccer balls
5/6 = around 0.83

The correct choice appears to be ...
... A) 4/15
Answer: Last option.
Step-by-step explanation:
For this exercise it is important to remember that a Right triangle is a triangle that has an angle that measures 90 degrees.
By definition, given a Right triangle, if you draw an altitutde from the vertex of the angle that measures 90 degrees (The right angle) to the hypotenuse, the measure of that altitude is the geometric mean between the measures of the two segments of the hypotenuse.
In this case, you have the Right triangle
given in the picture attached.
You can notice that
goes from the vertex of right angle (
) to the hypotenuse
. Therefore, it divides the hypotenuse into two segments. These are:
and 
Therefore,
is the geometric mean of the segments
and
.
