It depends on the weight of the assignment in the class
I wish you were using parentheses here. I must assume (without knowing for sure) that y ou mean
a - 3/7
----------
3 - a/21
The LCD here is 21, since 7 divides into 21 without a remainder.
Thus, multiply numerator and denominator by 21:
21a - 9
-----------
63 - a
You could leave this result as is, or you could factor out 3:
7a-3
3 ---------
63-a
We know from the given that the person earns 250 dollars
for every complete doll that he makes. Since he was only able to make 7 dolls
completely, therefore the total money he earned was:
<span>total money = $250 * 7 = $1,750</span>
This is my work. the answer would be 200 2/3.
Answer:
0.5%
Step-by-step explanation:
That percentage would be:
8 people
--------------------- = (1/200) = 0.005 multiplied by 100% yields 0.5%
1600 people
