What is the expanded form of 84.22
Ira Lisetskai [31]

Answer:

80 + 4 + 2/10 or 0.2 + 2/100 or 0.02. When I wrote the fractions, it really depends on what your teacher taught you to do.

Step-by-step explanation:

8 x 10 + 4 x 1 + 2 x 1/10 + 2 x 1/00

That is just the explanation for the equation.
