Answer:
0.6666 or [tex]\frac{1}{3}[/tex]
Step-by-step explanation:
Since this is a ratio problem we can simply use the rule of three to solve it. We need to multiply the diagonal values and divide by the remaining value to get the variable which in this case is x (how much life he has already lost)
15 minutes <=======> 1 life
10 minutes <=======> x
(10 * 1) / 15 = x
10 / 15 = x
0.6666 or [tex]\frac{1}{3}[/tex] = x
Finally, we can see that Farid has lost 0.6666 or [tex]\frac{1}{3}[/tex] in those 10 minutes
