Answer:
The reasonable estimate is 100.
Step-by-step explanation:
The given equation is 188 = m+80.
The nearest hundred to 188 is 200.
The nearest hundred to the digit 80 is 100.
Estimating the digits in the equation we have :
200=m+100
Or m=200-100=100.
The reasonable estimate for m in the equation 188=m+80 is 100.
