Short Answer 
Approximately 138,617 women in Tlaxcala have reported experiencing sexual abuse, which represents about 1 out of every 5 women in the region. This estimate is based on the total female population of approximately 693,083.
Step 1: Determine the Fraction of Women Affected
To start, we need to identify the fraction of women who have experienced sexual abuse. It is reported that 1 out of every 5 women has faced this issue. This can be expressed in fractional terms as:
- Fraction of abuse: 1/5
Step 2: Calculate the Total Number of Women
Next, we determine the total number of women in Tlaxcala who have reported suffering from sexual abuse. Given that there are approximately 693,083 women in the region, we multiply this total by the fraction calculated earlier:
- Calculation: 693,083 * (1/5) = 138,616.63
Step 3: Round and Present the Final Result
Finally, since we cannot have a decimal count of women, we round the result to the nearest whole number. This gives us a total of approximately 138,617 women in Tlaxcala who have reported having suffered sexual abuse in their childhood.
