I took 48÷24% to get the total number of crayons in the box because if you multiply a number by a percent you get whatever is like, 7% of 100, if you divide a number (48) by a percent (24%) you GET the original number (200) that was multiplied by the percent (24%) to get the number you HAVE (48). So, the total number of crayons is 200.
For this question all you have to do is times the 9 and 7 and put the denominator(in this case 8) underneath to make a fraction. The answer totals as 63/8 or 7 and 7/8.
