If a rooster laid 13 eggs and the farmer took eight of them and then another rooster laid 12 eggs and four of them were rotten, how many of the eggs were left?

1st rooster:
13-8=5

2nd rooster:
12-4=8

8+5=13

13 eggs left

The answer is 60.9774

One shot. if 60% of 10 is 6, then what is 70%? we know it would be seven (since 60% is mathematically 60/100, or 6/10, then 70% is 70/100, or 7/10) but we can check anyway using ratios: 6 : 60% = x : 70%*inverse multiplicationx * 60% = 6 * 70%*divide both sides by 60%x = (6 * 70%) / 60%x = 7and since he has made 6 shots already, he would need just one more to get 7 shots or 70%. if the explanation is too confusing, comment and i will try to
