Question

using prefixes: how many centimeters are in one meter? 100 cm how many kilograms are in one gram? __________ how many milliliters are in one liter? ________ how many nanometers are in one meter? __________ which is largest: 1 cm, 1 m, 1 nm, 1 mm, 1 km, 1 pm, or 1 mm?

Explanation:

Step1: Recall metric - prefix conversion

The prefix "kilo -" means 1000. So 1 gram = 0.001 kilograms or $\frac{1}{1000}$ kg.

Step2: Recall metric - prefix conversion for volume

The prefix "milli -" means 0.001. So 1 liter = 1000 milliliters.

Step3: Recall metric - prefix conversion for length

The prefix "nano -" means $10^{-9}$. So 1 meter = $10^{9}$ nanometers.

Step4: Recall metric - prefix values for comparison

The prefix "Mega -" (Mm) means $10^{6}$, "kilo -" (km) means $10^{3}$, "centi -" (cm) means $10^{-2}$, "milli -" (mm) means $10^{-3}$, "nano -" (nm) means $10^{-9}$, "pico -" (pm) means $10^{-12}$. So 1 Mm is the largest among 1 cm, 1 m, 1 nm, 1 Mm, 1 km, 1 pm, 1 mm.

Answer:

0.001 kg
1000 mL
$10^{9}$ nm
1 Mm
