Answers are:
16.
-1 - (-4) = 3
17.
-1-1/3 - (-4) = 2-2/3
18.
2 - (-1) = 3
19.
3-1/2 - (-1) = 4-1/2
20.
3-1/2 - 2 .= 1-1/2
21.
3-1/2 - (-1-1/3) = 4-5/6
Step by step: I took one point and subtracted the second point to get the length of each segment. You could also look at the ruler and count from one point to the other.
Remember when you subtract a negative, the two negatives become a positive
If 85 blinks = 15 minutes
then 51 blinks = x (cross multiply)
85 × x = 51 × 15
85x / 85 = (51 x 15) / 85
x = (51 × 3) / 17
x = 3 × 3
x = 9
so he blinked 51 times in 9 minutes
if 1 minute = 60 seconds
then 9 minutes = x (cross multiple)
1 × x = 9 × 60
x = 540
therefore 540 seconds passed when he blinked 51 times
