Answer: 40%
Step-by-step explanation:
There are 70 cookies in total.
The gingerbread cookies number 28.
The percentage that are gingerbread will therefore be:
= Number of gingerbread/ Total number of cookies * 100%
= 28 / 70 * 100%
= 40%
76.25 is the answer because 1525 divided by 20 equals 76.25
So the greatest common factor of 40 and 16 is 8
40/8 : 16/8
5:2
The simplest form of the ratio 40:16 is 5:2
