Change the compound fractions to simple fractions to subtract:5 \frac{3}{8} =  \frac{43}{8}  \\ 4 \frac{3}{4} = \frac{19}{4}
\frac{43}{8} - \frac{19}{4} = \frac{(43*4)-(19*8)}{8*4} = \frac{20}{32} = \frac{5}{8}

So Ben grew 5/8th of an inch

Hope that helps

Answer:

For every 15 students scoring in the 60's there were 9 students scoring in the 70's.

Step-by-step explanation:

Your first step would be to rewrite the numbers into an easier to understand form like fractions, 45/3 and 27/3. Then you divide both numbers by 3, so you get comparable numbers. 45/3= 15, 27/3=9.

Charlotte recorded the number of minutes she spent exercising in the past ten days: 9, 13, 5, 2, 9, 1, 14, 3, 5, 7. Find the med
Nuetrik [128]

Answer:

<u>The median is 7.</u>

Step-by-step explanation:

In order to find the median, you need to ut the numbers in either least to greatest form, or greatest to least (FIRST).

I'm gonna do both as an example.

Greatest to least:

14, 13, 9, 9, 7, 5, 3, 2, 1

Least to greatest:

1, 2, 3, 5, 7, 9, 9, 13, 14

<u><em>It is REALLY important that you use ALL of the numbers you are given, even if there are two or more of the same number.</em></u>

The next thing you need to do is find the number that is in the middle.

It will be the same for both least to greatest AND greatest to least.

You can either count one from either side, going in a pattern, OR you can count how many there is, divide it by 2, and whatever answer you get, count that many times over from one side.

In this case, your answer goes like this:

since there are 9 numbers, and 9 is not an even number, you will have only one median. Having 2 medians IS normal and it IS ok.

In this case, you want to go down one number (from 9) and divide that. So you do 8 divided by 2, which is 4. Count that many times over and you have your answer, 7.

I hope this helped you!

Have a great dayyyy

Abigail rides her bike with a constant speed of 12 miles per hour. How far can she travel in 45 minutes?
ohaa [14]
If she rides at 12 miles per hour, we know that 45 minutes is three quarters of an hour, therefore just workout:

3/4 x 12 = 9

So she would travel 9 miles in 45 minutes.
