You would say to yourself:-- If it has to be divisible by 5 and 9, then it's divisible by 45.-- The biggest 3-digit number is 999.-- 999 divided by 45 is 22.2-- So if I multiply 45 by only 22 and leave off the 0.2,I'll get the biggest one that's less than 999.-- 45 x 22 = 990 .
990 ÷ 45 = 22
45/22 is already an improper fraction. As a mixed number, it is 2 1/22.
n - 22 = 45(+ 22 on both sides)n = 67
