The ratio of chocolate chip cookies, snickerdoodles and oatmeal raisin cookies was 2: 5: 7. during the class party 12 chocolate chip cookies, 24 snickerdoodles and 36 oatmeal raisin cookies were eaten. now the ratio is 1: 3: 4. how many cookies were ar the party to start?

127 cookies

Step-by-step explanation:

1. If you look back to the text you will see that 12 is 1 in 1:3:4 and you multiply that by 2. 12 * 2 = 24.

2. Divide 24 by 3 and that gives you 8 than times it by 5 for it to give you 40

3. Divide 36 by 4 and that equals to 9 than multiply it by 7 which that gives you 63

4. Add 24, 40, and 63 for it to give you 127

the range is 19

step-by-step explanation:

the range is biggest number minus the smallest, so in this case it would be

41 - 22 = 19

1/4 and 8/3 because:

the reciprocal if 4 is 1/4 because 4 is used as 4/1 and the opposite of that is 1/4. the opposite of 3/8 is 8/3 so that is the answer.
