If matt filled a 2 1/5 cup container, how many 1/5 cups would he need to use

well since it is out of five, and there is 2 whole numbers, 2 times 5 would equal 10 , but you still have 1/5 left so you would do 10 plus 1 which would equal 11. He would need to use 11 cups.

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
