Question

Dont understand this question it confucing

Answer 1

so, let's see, Amber made 3 penalty shots off 4, now, 3 out of 4 is 75% or 3/4. So she's 75% of the time effective.

Lindsay has made 4 out of 6 penalty shots, 4/6 or 2/3, that's about 66% effectiveness.

Li has made 2 out of 3 penalty shots, that's 2/3, that's about the same 66% effectiveness.

so, which fraction is highest 3/4, or 2/3 or 2/3? neverminding the percentages, let's multiply all by the LCD, let's see from 4, and 3, and 3, the LCD is 12.

so, let's multiply all of them by 12, to get rid of the denominator, to see which is highest.


`\bf 12\cdot \cfrac{3}{4}\implies \boxed{9}\qquad \qquad 12\cdot \cfrac{2}{3}\implies \boxed{8}`

notice, Amber has the higher effectiveness rate, to make it through in the penalty kick.
