When a number is divided by 6, the remainder is 3 and when it is divided by 8, the remainder is 5. What's this number?

If you subtract 3 from this number, it is a multiple of 6 and 8. Therefore: [6,8] = 24

This number is: 24-3=2 1 or 24*2-3=45 ... It can be recorded as 24n-3(n stands for a natural number greater than 1).

Of course, for the third grade students, you can't say that.

Why don't you list it?

The number matching 6: 39152127 33 39 455157 63 69 7581. ......

Number matching 8: 5132129 37 45 53 6169. ......

This means that there are 2 1 45 69 eligible numbers. ......

The question "What is this number?" Is ambiguous, it should be "what is the minimum number?" "What will this number be?"
