Pick an appropriate non-equivalent decimal for 0.05.
a.
0.050
b.
0.50

a.
5.112000
b.
5.1120
c.
5.11200
d.
5.0112


Solution:

We may add decimal places to a number without changing the value of the number by attaching one or more zeros to the right of the last decimal place.

5.1120, 5.11200 and 5.112000 are equivalent to 5.112.

5.0112 is less than 5.112.

5.112 and 5.0112 are not equivalent decimals.
