20 is the 1 significant figure to 21.93.

Step-by-step explanation:

Given:

The number 21.93 to 1 significant figure.

A significant figure is a digit in a number that gives you information about the numbers size.

Rounding  to 1 significant figure means looking at the 1st digit of the number.

Here, the first digit is 2 and 2 is in tens place.

So, 2 in tens place gives us 20 as the size , thus next number next to 2 is 1.

So, on rounding to one significant figure we write it as 20.

Therefore, 20 is the 1 significant figure to 21.93.
