Rebecca baked 100 cookies for the state fair. Sixty were oatmeal, 20 were lemon, and 20 were chocolate. What percentage of cookies were NOToatmeal? (Explain for brainlist)

40%

Step-by-step explanation:

If 60 out of 100 were oatmeal, 60% would be oatmeal.

20 lemon + 20 chocolate  = 40

40 out of 100 is 40%

To confirm add 60 and 40;

60+40=100

40% were NOT oatmeal. ( i think)

Step-by-step explanation:

Sense there is 100, that makes it easy.

60% is oatmeal

20% is lemon

20% is chocolate

20 + 20 = 40

So its 40% were NOT oatmeal

I think that's right.
