35.

She baked 21, Sunday she baked twice as many so 21x2 = 42
then, 4 cookies fell. 42 - 4 = 38. After that she packaged 3 cookies, 38 - 3 = 35.

Answer:

the answer is 35 over 102 or 35/102

Step-by-step explanation:

so first we turn that 1 and 1/5 into 6/5 and then we flip the numbers into 5/6. so now we multiply 7/17 x 5/6 = 35/102. The Number can not be reduced.
