Carter has 60 balloons. 4/12 of the balloons are black, and 3/12 of the balloons are white. the rest of the balloons are red. which series of calculations shows how many red balloons carter has?

Divide 60 by 12 and multiply that answer by 7. Take that answer and subtract it from 60, the number you have left over should be the number of red balloons you have.

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
