272 is the partial product of 34 and

.

680 is the partial product of 34 and
.

20

To find the missing number in each statement, we need to divide the given partial product by the known number:

1. For 272 as the partial product of 34 and _, we divide 272 by 34:
272 ÷ 34 = 8

Therefore, 8 is the missing number.

2. For 680 as the partial product of 34 and _, we divide 680 by 34:
