Answer:
0.25
Step-by-step explanation:
Given : 0.3 was rounded by 1SF
To Find: what is the lower bound
Solution :
Writing upper bounds and lower bounds = We always go half the rounded value up and half the rounded value down
Since we need to find the lower bound
So, lower bound of 0.3 :
=0.3 -0.05
=0.25
Thus the lower bound of 0.3 is 0.25
