0.3 was rounded by 1SF what is the lower bound?

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
