78 divided by 4 = 19.5 so 19 and a half days to climb up the well.
(8*10^13)/(3*10^3)
remember
(ab)/(cd)=(a/c)(b/d)
we can split them up
also
(x^m)/(x^n)=x^(m-n)
so
(8*10^13)/(3*10^3)=(8/3)((10^13)/(10^3))=(8/3)(10^(13-3))=(8/3)(10^10)
answer is (8/3)*10^10 times
the power of 10 is 10
Answers:
1: No, 10/12 Simplified is 5/6, and 15/30 simplified is 1/2
2: Yes, 1/5 / 3/5 Simplified is 1/3, and 1/4 / 3/4 simplified is 1/3
3: 60 words, You do 300 divided by 5, and you get 60 per minute
4: 240 words, You take the 60 per minute, and you multiply is by 4.
5: 24 doughnuts, 20x3 is 60 minutes. So, 12 doughnuts in one hour. Multiply is by 2, and you get 24 doughnuts per hour.
6: Walmart, To find out how much it costs, you so 1.25 / 5, and 0.80 / 2. So, Walmart is 0.25 per pack, and Ingles is 0.40 per pack. So, you can automatically tell that Walmart is cheaper, meaning the better buy.
-2 -9 so that means the minimum of j is 9
Good luck.
You can work this several ways. One way is to figure out how many stickers each has, then write their relationship as a ratio.
Here, Lisa will have 12/2 = 6 more than half the total number of stickers, hence 36. John will have the remaining 24. Their ratio is
Lisa's stickers : John's stickers = 36 : 24 = 3 : 2
Another way to look at this is to realize 12 divides 60 into 5 equal parts. The ratio that will total 5 parts with one number being 1 larger than the other is 3 : 2.
Lisa's stickers : John's stickers = 3 : 2
