Question

Arrange the following decimals in descending order:
2.3, 0.5, 0.6, 9.8

• A. 2.3, 9.8, 0.5, 0.6
• B. 9.8, 0.5, 2.3, 0.6
• C. 9.8, 2.3, 0.6, 0.5
• D. 9.8, 2.3, 0.5, 0.6

Answer 1

The correct option is C 9.8, 2.3, 0.6, 0.5

Decimal number	Ones	Tenths
2.3	2	3
0.5	0	5
0.6	0	6
9.8	9	8

Since 0.5 and 0.6 have the same whole number, we need to compare the first digits to the right of the decimal point in these decimals.
Since 6 tenths $>$ 5 tenths, we have 0.6$>$ 0.5.
Since 9$>$2$>$0, arranging the decimals in descending order we have:
9.8 $>$ 2.3 $>$ 0.6 $>$ 0.5.
