Question

Arrange the following in increasing order:

0.1, 0.9, 0.5, 0.7

• A. 0.7< 0.5< 0.1< 0.9
• B. 0.1 <0.5 <0.7 <0.9
• C. 0.5 <0.1 <0.7 <0.9
• D. 0.9 <0.5 <0.1 <0.7

Answer 1

The correct option is B 0.1 <0.5 <0.7 <0.9

According to their places on the number line,
0 is at one place left of decimal to every number i.e., at units place.

Then one place to the right of the decimal(i.e., tenths place) we have 1, 9, 5, 7.
i.e., 1 < 5 < 7 < 9
According to their places on the number line,
0.1 < 0.5 < 0.7 < 0.9
