The answer is 2 bc I got it right on a quiz
No, 1 and 3/9 can be simplified to 1 and 1/3
1) 1 dot
2) figure 1 + 3 dots
3) figure 2 + 5 dots
4) figure 3 + 7 dots
5) figure 4 + 9 dots
and keeps going....
The next figure, takes the solution of last figure and add odd number in increasing order.
In this type of problem, find a matter.
45 minutes equal to 2700 seconds.
