Find the missing number of each unit rate. 155 = ?1 246 = ?1<br><br>worth 15 points!!!
alexgriva [62]

This is an incomplete question, the correct question is given below.

Find the missing number of each unit rate \frac{15}{5}=\frac{?}{1} and \frac{24}{6}=\frac{?}{1}

Answer : The missing number of each unit rate of \frac{15}{5}=\frac{?}{1} and \frac{24}{6}=\frac{?}{1} are, 3 and 4 respectively.

Step-by-step explanation :

As we know that a unit rate is a rate in which 1 is present in denominator.

Or we can say that,

A unit rate is also called a single unit rate that means it will compare 1 unit of some quantity to a different units of a different quantity.

As we are given that that unit rates:

\frac{15}{5}=\frac{?}{1} and \frac{24}{6}=\frac{?}{1}

Now we have to determine the missing number of each unit rates.

So, we can write the given expression as:

\frac{15}{5}=\frac{?}{1}

When are dividing 15 by 5, we get:

\frac{15}{5}=\frac{3}{1}

Thus, the missing number is, 3

And

\frac{24}{6}=\frac{?}{1}

When are dividing 24 by 6, we get:

\frac{24}{6}=\frac{4}{1}

Thus, the missing number is, 4

There are 1200 students at Sophie’s school. One student’s name will be drawn at random to win a new bike. Hannah and Ethan are S
fomenos
Hi Mackenzie. 

Given that we have a probability question with the term "or", we are going to be adding individual probabilities.
We have Ethan, Hannah, and Sophie all included with the drawing.
This means we need to add each of their individual probabilities, 1/1200, together.

1/1200 + 1/1200 + 1/1200 = 3/1200;
To simplify: 1/400

Your answer is:
The probability of Ethan, Hannah, or Sophie being drawn is 1/400.

I hope this helps!
