n - 22 = 45
(+ 22 on both sides)
n = 67
a number increased by -22 is 45. find the number
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

Has it got to be "exactly" 45 more, or "at least" 45 more?
A 4-digit number divisible by both 5 and 9 must be divisible by their least common multiple, which is 45. To find a 4-digit number divisible by 45, we need to find a number that ends in 0 and is divisible by 45. The smallest 4-digit number that fits these criteria is 1005 (45 x 22 = 990, and adding 15 gives us 1005).
