To solve this first we have to find out how many seconds are in 15 minutes.
So, 15 x 60 since there is 60 seconds in a minute, and of course there are 15 minutes.
15 x 60 = 900 seconds.
Now we need to find out about how many seconds does it take George to blink once. So we divide 900 seconds by 85 blinks.
900 / 85 = About 11 seconds for one blink.
Now we use the rate of 1 blink = 11 seconds and multiply. Since they said 51 blinks you would multiply 51 blinks by 11 seconds.
51 x 11 = About 561 seconds.
Answer: About 561 seconds passed in 51 blinks.

Change mixed numbers to improper fractions. Then change division to multiplication by the reciprocal.
1 1/2 divided by 3/5=
(3/2) * (5/3) = 5/2 = 2 1/2
#3
(5/9) divided by (5/3)
(5/9) * (3/5) =3/9 = 1/3
