$7.05,7.048,7.002\text{and}7.2$

• A. $7.2,7.05,7.048,7.002$
• B. $7.002,7.048,7.05,7.2$

Answer 1

The correct option is B $7.002,7.048,7.05,7.2$

Ascending order means arranging the numbers from smallest to largest.

To compare the numbers, we align the decimal points such that only like terms are compared.

O	.	t	h	th
7	.	0	5	0
7	.	0	4	8
7	.	0	0	2
7	.	2	0	0

We start comparing from the farthest left column and move towards the right.

As digits in the units column are same, we compare the tenths column.

As $2>0$, 7.2 is the largest number among these.

As rest of the numbers have zero in the tenths column, compare the hundredths column.

As $5>4>0$,

$\therefore 7.05>7.048>7.002$

Hence, $7.002<7.048<7.05<7.2$

The ascending order is:

$7.002,7.048,7.05,7.2$
