Question

Jannat thinks of a number, f.

She rounds f to 1 d.p.
She then rounds the result to the nearest integer.
Her final number is 27.
What is the smallest value that f could have?

Answer 1

The smallest value that f could have is 26.45.

Step-by-step explanation:

To find the smallest value that f could have, we need to work backwards.

Since the final number is 27, we know that after rounding to the nearest integer, the result is 26.5.

Therefore, the number after rounding to 1 decimal place must be 26.45.

The smallest value that f could have is 26.45.
