Usually, you CAN'T turn a fraction into a whole number.

You can ONLY do it when the top number is a multiple
of the bottom number. Otherwise, it's not possible.

IF the top number is a multiple of the bottom number,
then take the bottom number, and divide both the top
and the bottom of the fraction by it. Then the top number
will be the whole number that's equal to the original fraction.

Examples:

12 / 5 . 12 is not a multiple of 5 , so there is
   NO whole number that's equal to 12/5 .

   5 / 12 . Same thing. 5 is not a multiple of 12 .

   12 / 3 . 12 is a multiple of 3 .
Divide top and bottom by 3 .
Then you have 4 / 1 .
   4 is the same as 12/3 .

A recipe uses 2 cups of flour to make 18 cupcakes. How much flour is needed to make 27 cupcakes?

drek231 [11]

Answer:

3 cups

Step-by-step explanation:

we can solve this by setting up ratios

$\frac{2 cups}{18 cupcakes} = \frac{x}{27 cupcakes}$

cross multiply:

$(2)(27) = 18x$

$54 = 18x$

solve for x

$x = 3 cups$

A sample of 80 Valencia oranges showed a mean weight of 5.5 ounces with a standard deviation of 0.2 ounces. Obtain a 95% confide

BartSMP [9]

Answer:

[ 5.456, 5.544]

Step-by-step explanation:

Confidence interval can be defined as a range of values so defined that there is a specified probability that the value of a parameter lies within it.

The confidence interval of a statistical data can be written as.

x+/-zr/√n

Given that;

Mean x = 5.5 ounces

Standard deviation r = 0.2 ounces

Number of samples n = 80

Confidence interval = 95%

z value (at 95% confidence) = 1.96

Substituting the values we have;

5.5+/-1.96(0.2/√80)

5.5+/-1.96(0.022360679774)

5.5+/-0.043826932358

5.5+/-0.044

= ( 5.456, 5.544) ounces

Therefore the 95% confidence interval (a,b) = ( 5.456, 5.544) ounces
