12x6 is 72 (mental math)
Then add three zeros to 72.
12000x6= 72000
Answer:
I think the reference ratio given is wrong so the right one is
8:508:508:5
Step-by-step explanation:
Given that,
8:58:58:5
We want to find which of the option is equivalent to the given ration
Option A.
16:1016:1016:10
Divide each of the ration by
Then,
16÷2:1016÷2:1016÷2:10÷2
8:508:508:5
Option B
50:8050:8050:80
Divide through by 10
50÷10:8050÷10:8050÷10:80÷10
5:805:805:8
Option C
48:3048:3048:30
Divide through by 6
48÷6:3048÷6:3048÷6:30÷6
8:508:508:5
Option D
32:2032:2032:20
Divide through by 4
32÷4:2032÷4:2032÷4:20÷4
8:508:508:5
Option E
64:3564:3564:35
Divide through by 8
64÷8:3564÷8:3564÷8:35÷8
This doesn't have a factor
So the ratio still retain
64:3564:3564:35
So to analyse the solution,
I believe the reference ratio given is wrong, so I think the reference ratio about be 8:508:508:5
So, from the option, the equivalent to the given ratio are options A, C, and D
Answer: Last option.
Step-by-step explanation:
Let be "s" the unit price of the smaller box and "l" the unit price of the larger box.
According to the information given in the exercise, the smaller one is a 17-ounce box which costs $2.89. Therefore, in order to find the value of "s", you need to divide $2.89 by 17 ounces. This is:
You know that the larger box has 24 ounces and it costs $3.29.
Therefore, in order to find the value of "l", you need to divide $3.29 by 24 ounces. This is:
Finally, find the difference:
or 
Therefore, you can conclude that the larger box is better buy because it is approximately 3.3 cents cheaper per ounce.
