There are four hundred participants in the local Thanksgiving 5K race. If 51% of the participants are female, what is the ratio

Paha777 [63]

Answer:

51:49 is the ratio of female participants to male participants.

Explanation:

Percentage of females in the race = 51 %

Percentage of males in the race = 100% - 51 % = 49%

Total participants in race = 400

Number of women participants = $51% of 400=\frac{51}{100}\times 400=204$

Number of men participants = $49% of 400=\frac{49}{100}\times 400=196$

Ratio of female participants to male participants :

$\frac{204}{196}=\frac{51}{49}=51:49$
