Question

Arrange the decimals 7.774, 7.775, and 7.776 in their descending order.

• A. $7.774>7.775>7.776$
• B. $7.775>7.774>7.776$
• C. $7.776>7.774>7.775$
• D. $7.776>7.775>7.774$

Answer 1

The correct option is D $7.776>7.775>7.774$

Write the numbers in place value table and starting from left compare the digits in each place value until the first pair of digits become different.


From the place value table, digits are different in the thousandths place.

As we know, $4<5<6$

So, $7.774<7.775<7.77$.

∴ Descending order of the given decimals is: $7.776>7.775>7.774$
