Question

Mr. Chang bought 264 pencils to divide evenly among his 22 students. How many pencils did each student receive?

11
12
13
14

Answer 1

12

Explanation:

264 divided by 22 is 12

Answer 2

`(264)/(22) = (132)/(11) = 12 \\`

_________________________________

Point :

`11 * mn = m(m + n)n`

For example :

`11 * 11 = 1(1 + 1)1 = 121`

`11 * 13 = 1(1 + 3)3 = 143`

`11 * 27 = 2(2 + 7)7 = 297`

________________________________

`(286)/(11) = (2(2 + 6)6)/(11) = 26 \\`

`(891)/(11) = (8(8 + 1)1)/(11) = 81 \\`
