34 x 23 = 782
Let the unknown number be x: 3x-23 = 34 3x = 34+23 3x = 57 x = 19
24*27 = (23*3) * 33 = 23*34
3240 = 23 x 34 x 5
The peculiar aspect of your question is those gaps between numbers; it is fairly simple to add 523 and 334, but you have 5 23 and 3 34; it is not clear what you are trying to say. Possilby you mean 5 x 23 and 3 x 34. But it's hard to be sure.
Well, 23 is 10+10+3. So it is easy to multiply 10 x 34 = 340 10 x 34 = 340 and 3 x 34 = 102. Just break it down to easy multiplication. Now all you have left to do is add 340+340+102=
34 x 23 = 782
Let the unknown number be x: 3x-23 = 34 3x = 34+23 3x = 57 x = 19
24*27 = (23*3) * 33 = 23*34
assuming 23 and 34 mean 2/3 and 3/42/3 x 4/4 = 8/123/4 x 3/3 = 9/12so 3/4 is 1/12 more than 2/3
3240 = 23 x 34 x 5
1 with 11 remaining 34 - 11 = 23 = 1 x 23
782

9/17 ÷ 3/34 = 9/17 x 34/3 = (9 x 34)/(3 x 17) = 9/3 x 34/17 = 3 x 2 = 6
