Answer:

225%

Step-by-step explanation:

Find the difference between the two prices, then divide it by the original price:

78 - 24 = 54

54/24

= 2.25

So, the markup rate is 225%

Answer:

105 11/12

Step-by-step explanation:

With mixed numbers you can also write them as functions so 5 11/12 could also be written as 5+11/12.

Once you have rewritten the mixed number it's simply a matter of addition: 100+5+11/12

At the grocery store, 3 apples cost $0.65. What is the cost of 8 apples?

Mars2501 [29]

Answer:

$1.76

Step-by-step explanation:

First we need to figure out the cost of one apple.

To do this, divide the cost by the amount.

That's .65/3, which equals .216666, but we should round that number to .22

So if one apple is 22 cents, and we need to know how much money 8 apples is, we times .22 by 8, which gives us 1.76

Hope this helps :))

Answer:

3 5/6 cups of flour

Step-by-step explanation:

You want the total amount so we add both fractions together.

1 1/2 + 2 1/3

I prefer to convert both to an improper fraction and then convert back to a mixed number, so;

1 1/2 = whole number (1) x denominator (2), add numerator (1), = 3, put this over the old denominator (2) = 3/2

2 1/3 = whole number (2) x denominator (3), add numerator (1), = 7, put this over the old denominator (3) = 7/3

Now we add the 2 improper fractions, so we have to convert them both to a common denominator. The LCM of 2 and 3 is 6, so it will be over 6.

3/2 = to get from 2 to 6, you multiply by 3, numerator (3) x 3 = 9, over 6 = 9/6.

7/3 = to get from 3 to 6, you multiply by 2, numerator (7) x 2 = 14, over 6 = 14/6.

9/6 + 14/6 = 23/6

Now we change back into a mixed number, how many times do 6 go into 23? 3 (6x3=18), as 4 would be 24.

So our whole number is 3

What is left goes over our denominator (6): 23 - 18 = 5.

So your answer is 3 5/6 cups of flour.

Kara is sorting buttons by length for a craft project. The line plot shows the length of each button. If Kara lines up all the 3

likoan [24]

Answer:

2 and 1/4 or 2.25. Both numbers are the same.

Step-by-step explanation:

Hi,

Please see the picture I had to upload in order for this question to be complete. Please also note that Kara has 3 buttons in the 3/4 length. You have to sum up only those in that length and ignore the ones in different lengths.

It is a very simple multiplication, and there are 2 ways to do so. You can use either fractions or integer numbers. See the 2 options below:

3/4 (fractions) = .75 (integer numbers)

Option one - 3 * 3/4 = 9/4 which is represented by 2 and 1/4.

Option two - 3 * .75 = 2.25

Have a good one!
