You know that you need two already to make one hexagon. So, if you multiply, or add two four times, 2+2+2+2, you would get eight.
Fraction: 1/512
decimal: 0.001953
12 times 34 is 408. Hope that helped.
Answer:
It will take both of the brick layers twelve and half days
WE know 1 day = 24 hours
To find number of hours spent on each activity, we multiply the corresponding percentage by 24
School : 25 % --> 0.25 * 24 = 6.00 hrs
Eating : 10 % ----> 0.1 * 24 = 2.40 hrs
Sleep : 40 % ----> 0.4 * 24 = 9.60 hrs
Homework: 10 % ---->0.1 * 24 = 2.40 hrs
Free time: 15 % -----> 0.15 * 24 = 3.60 hrs
