Answer:
G. Carla, Brenda, Marci, Susan
Step-by-step explanation:
The time given for all participants are in decimals except for that of Marci and Carla which are given in the form of mixed fractions.
Convert the mixed fractions into decimals, then compare the figures together to do the ranking.
Marci = [tex] 46\frac{49}{50} = \frac{2,349}{50} = 46.98 [/tex]
Carla = [tex] 46\frac{9}{10} = \frac{469}{10} = 46.9 [/tex]
The first four finishers from the 1st to the 4th are:
1. Carla - 46.9
2. Brenda - 46.97
3. Marci - 46.98
4. Susan - 47.21
