Question

Choose the smaller number among 1.02 and 1.20

• A. 1.20
• B. 1.02
• C. both are equal
• D. insufficient data to compare

Answer 1

The correct option is B 1.02

Let's arrange the given numbers in the place value table.

O	.	t	h
1	.	2	0
1	.	0	2

Starting from the left end,

1. The digits in the ones place are equal for both the numbers (1.20 and 1.02)
2. Compare the digits in the tenths place. As 2 > 0, hence, 1.20 > 1.02

$\therefore$ 1.02 is smaller.
