Question

0.1+0.9 it is having how many significant figures​

Answer 1

Step-by-step explanation:

two significant digits

The number "10." is said to have two significant digits, or significant figures, the 1 and the 0. The number 1.0 also has two significant digits. So does the number 130, but 10 and 100 only have one "sig fig" as written. Zeros that only hold places are not considered to be significant.
