44 * 6 = 264

264 / 8 = ......... erasers in each caddy.

(36 * 8) + (45 * 6) = ....... slices of pizza

28 * 6 = 168

168 / 4 = ....... students in each bus.

Hint: 64/27 = 2 10/27

Can you show us how..?

I understand my mistake now 179, 197,,,

ignore my message, i'll do it again

107, 109, 117, 119, 127, 129, 137, 139, 147, 149, 157, 159, 167, 169, 170, 171, 172, 173, 174, 175, 176, 177, 178, 179, 187, 189, 190, 191, 192, 192, 193, 194, 195, 196, 197, 198, 199 (37) 

207, ... , 299 (37)

...

700, ... , 799 (100)

...

900, ... , 999 (100) 

37 * 7 = 259

259 + 100 + 100 = 459

777 and 999 (- 2) and 171/191, 272/292, 373/393, 474/494, 575/595, 676/696, 797, 878/898, 979 (- 16)

(- 16) - (- 2) = (- 18)

459 - 18 = 441

So there are (457 - 18 =) 441  numbers that at least have one 7 or one 9 as digits.

Correct me if I am wrong. (probably wrong)

1) x = \(\pm \mbox{ } 4\)

2) x = 4

3) 6x = 4 | :6

     x  = 2/3

4) 2y = 0 | : 2

      y = 0

5) 7(a + 3) = 3a + 27 | distribute

    7a + 21 = 3a + 27 | - 21

           7a  = 3a + 6   | - 3a

            4a = 6           | : 4

              a = 3/2
