A. Personally if i was given these 2 options i would take the choice of drawing 2 bills from the bag per week.
B. Yes, i do not think pulling 2 bills from the bag is a good way to make money.
A. You could either get 10$ per week or you could get, 2$ 6$ 6$ 10$ 11$ 11$ 15$ 15$ now this depends largely on luck but logically 5 out of 9 times you will get 10 dollars or more so there is a higher chance you get more money from drawing money.
B. It is a good way to make money because 2/9ths of the time you will get 15$ and for every time you get 6$ you will get an equal amount of 15$ and you will get 21$ in the 2 weeks so it adds up, if you have bad luck or do this for a short amount of time then you could be losing out but if you have an average amount of luck then it will be worth the chance.
Answer:
I'm guessing 3/2
Step-by-step explanation:
I can see the pattern that it's doing down, up and then down again
7/2 to 6/3
5/4 to 4/9 and so on
Answer: C $1.51
To solve this, start with a proportion. Put the CPI numbers on the left and the apple juice prices on the right.
You will have:
82.4/130.7 = 0.95/x
Cross multiply to solve and you will get the price of the juice is $1.51.
d=28g I might be wrong, but we can find this by dividing 140 by five, which equals 28.
So I think maybe the example for the first problem created some confusion, and you may want to have your child take another look.
If we numbered the top half 1 to 9 going from left to right, numbers 1, 2, 6, 7 and 8 are right. They worked because the top number (numerator) perfectly fit into the bottom number (denominator). This is not true for the rest.
The key is to find the largest number that you can think of that will go into BOTH the top and the bottom evenly.
So for number 3: 18/24; 18 does not fit evenly into 24. The highest number that will fit into both is 6, so you divide both top and bottom by 6 and your answer is 3/4.
Number 4: 45/54; the highest number that goes into both is 9, so you divide both top and bottom by 9 and your answer is 5/6.
Number 5: 55/66; the highest number that can go into both is 11, so the answer is 5/6.
Is this making sense?
The bottom, numbering 1 to 9 from left to right. The correct ones are 1, 6 and 9.
For 2: 14/41 is about 15/40. Both can be divided by 5, so the answer is 3/8.
For 3: 20/81 is about 20/80, and 2/8 is close, but can still be divided by 2, so the answer is 1/4.
For 4: 24/49 is closer to 25/50 than 20/50. 25/50 can be divided by 25, so the answer is 1/2.
For 5: it was all correct, but the answer can be further reduced from 2/8 to 1/4.
For 7: 23/72 is about 25/75, and 25 goes into both, so it reduces to 1/3.
For 8: 13/21 is about 15/20, and 5 goes into both, so the answer is 3/4.
As your child continues to learn this, remember that if he or she gets an answer like 2/6 or 6/12, they should ask themselves if they can further reduce the fractions- 2/6 reduces to 1/3, and 6/12reduces to 1/2. I know it's confusing, but they do get the hang of it with practice
