Question

In a drawing class, Luke discovered that his wooden pencil is 6.7 cm long and his friend's pencil is 6.9 cm long. Who has the longer pencil?

• A. Luke has the longer pencil.
• B. Luke's friend has the longer pencil.
• C. Cannot be determined.

Answer 1

The correct option is B Luke's friend has the longer pencil.

To compare the decimal numbers, we align the decimal points.

$6.7$
$6.9$

Starting from the left end,

1. We find that the digits in the unit place are equal for both the numbers.
2. Comparing the tenths place digit, we find that 9 is greater than 7. Hence, 6.9 > 6.7.

$\therefore$ Luke's friend has the longer pencil.
