Benito had 10 days of vacation. he spent 1/5 of his vacation fishing. he spent 30% of his vacation at soccer camp. he spent the rest of the time at the beach. what percent of his vacation did benito spend at the beach?

If Benito had 10 days of vacation, then:

1/5 of this time is 20%
Soccer camp is 30%

10 days are 100%, so if he spent 20% of his time fishing and 30% at soccer camp, then he spent 50% at the beach:

100% - (20% + 30%) = 100% - 50% = 50%

Benito spend 50% of his vacation at the beach.
