Question

using the digit 0 to 9 and not repeating the digits,write the smallest three digit number that have a horizontal line of symmetry.​

Answer 1

Answer:

308

Step-by-step explanation:

In digits 0 to 9, only 3 digits have a horizontal line of symmetry which includes 0, 3 and 8.

Among 0, 3 and 8, '0' is the smallest but we can not from 0 as zeros located to the left of the first non-zero digit are not significant.

We are restricted to write the smallest 'three' digit number so we have to start from any non-zero digit which in this case is 3.
