<h3>What are ratio and proportion?</h3>

A ratio is a collection of ordered integers a and b represented as a/b, with b never equaling zero. A proportionate expression is one in which two items are equal.

The equation is given below.

12.5 mg : 5 mL = 24 mg : x mL

Then the value of x will be

12.5 / 5 = 24 / x

          x = (24 × 5) / 12.5

          x = 9.6 mL

More about the ratio and the proportion link is given below.

trapecia [35]

An equal-sized spinner is used to model probabilities

The spinner should have 4 equal sections

The number of friends is given as:

\mathbf{Friends = 3}

When Elisondra is included, the total number of people that went to the restaurant is:

\mathbf{n = Friends + 1}

Substitute 3 for Friends

\mathbf{n = 3 + 1}

Add 3 and 1

\mathbf{n = 4}

The number of people that went to the restaurant is the number of equal sections of the spinner.

Hence, the spinner should have 4 equal sections
