Answer:

16 x 0,75

(0,75 = 3/4) so you could take 3 x 16 = 48 and then take 48/4 and the answer should be 12 but the percent is 75%

Find the sum or different 11/18-1/6
ira [324]

Answer:

4/9

Step-by-step explanation:

11/18-1/6


The first step is to get a common denominator, which is 18.  We can multiply 1/6 by 3/3 to get the denominator to 18


11/18 - 1/6 *3/3

11/18 - 3/18

8/18

Now we can simplify the fraction by dividing the top and bottom by 2

4/9
