Let us assume the unknown number in the question to be = x Then 160% * x = 32 (160/100) * x = 32 16x/10 = 32 16x = 32 * 10 16x = 320 x = 320/16 = 20 So from the above deduction we can easily conclude that the unknown number in the question is 20. Be very careful about the calculation and the cross multiplication part of the problem. Other than that there is nothing complicated in the question.
Noah has 75 marbles. Noah has more marbles. this is because 34 times 3 is equal to 102. since michelle takes 9 marbles from EACH box, 9 times 3 is 27. 102 minus 27 is 75
