Keli measures the chair seat with a centimeter ruler and with a meter stick. Will Keli count more units when she measures the length of the seat with a centimeter ruler or with a meter stick
A
The Correct Answer and Explanation is:
Keli will count more units when she measures the length of the seat with a centimeter ruler than with a meter stick.
Explanation:
The key difference between a centimeter ruler and a meter stick lies in their units of measurement and the length they represent.
- Centimeter Ruler: A centimeter (cm) is 1/100th of a meter. When Keli uses a centimeter ruler, she will be counting in smaller units. This means she will be able to divide the length of the chair seat into more smaller parts. For example, if the chair seat is 50 cm long, Keli will count 50 units (since each unit is 1 cm).
- Meter Stick: A meter (m) is 100 centimeters. So, when Keli uses the meter stick, each unit she counts represents a longer length (1 meter). For example, if the chair seat is 50 cm long, she will only count 0.5 units (since 50 cm is 0.5 meters). This is far fewer units than counting with a centimeter ruler.
Because the centimeter ruler measures in smaller increments, Keli will count more units to cover the same distance compared to the meter stick. In fact, a meter stick only allows for the counting of whole meters, so it divides the length into fewer units overall. Therefore, measuring with the centimeter ruler results in more unit counts because the measurement unit is smaller.
