Answer:
B. 18
Step-by-step explanation:
Her first two arrows landed on the same circle with 14 points. This means that 1 arrow in that circle = 7 points.
The second time, one arrow landed on the circle that carry 7 points per arrow, and the next inner circle would carry = 16 - 7 = 9 points
Therefore, if in her third throw, the two arrows landed in the inner circle that has 1 arrow recording 9 points, she would get = 9*2 = 18 points
Yes, 5:4 is the simplified form of 25:16. 25 divided by 5 is 5 (the lowest possible number it can be made into). 16 divided by 4 is 4 (also the lowest possible number it can be made into).
