Show your mastery of multiplying fractions by using the sketchpad to find the product of 3-4 x 37
diamong [38]

Answer:

\frac{111}{4}

or

27 \frac{3}{4}

Step-by-step explanation:

Any regular whole number (37 for example) is over one so it would look like \frac{37}{1}. Multiplying fractions involve just multiplying the numerators and denominators together, therefore it would look like \frac{3}{4}×\frac{37}{1}. Now just multiply the top and bottom numbers together and this will leave you with \frac{111}{4} . But if you'd like to make it into a mixed number (more simplified version of \frac{111}{4} ) then you would get 27 \frac{3}{4}.

there are 4 sections of seats I the playhouse theatre. each section has 7 groups of seats.each group has 25 seats. how many seat
Nady [450]
To find the number of seats, let's do it using multiplication!

First, to see how many seats are in one big section of the theatre, multiply 7 groups of seats by 25 seats:

7 x 25 = 175

Now, knowing this, multiply 175 by 4 to get the total number of seats in the theater!

175 x 4 = 700

Therefore, there are 700 seats in the theatre.

Hope this helps!

What is the slope of the line shown?<br><br> -7/9<br> 9/7<br> 7/9<br> -9/7
SpyIntel [72]

To find slope, we must find the change in y values divided by the change in x values, also called the rise/run. This is modeled below:

Slope = m = (y1 - y2)/(x1-x2) = (6-(-3))/(1 - (-6)) = (6+3)/(1+6) = 9/7

We can check that this answer is correct by consulting the graph. The graph shows a positive correlation (means that the slope should be positive), and if you count the graph unit squares, you get that the graph moves up 9 squares and over 7 squares between the two points shown, letting us know we got the right answer.

Hope this helps!
