To solve the problem “56 is what percent of 70?”, Noah uses the double number line below. On the double number line, write the correct numbers at each unlabeled tick mark. Then solve the problem. A double number line with 5 tick marks. The first 2 tick marks are toward the left end of the number line and the other 3 are toward the right end. For the top number line, the tick marks are 0, 7, unlabeled, unlabeled, 70. For the bottom number line, the tick marks are 0%, 10%, unlabeled, unlabeled, 100%.
