Question

1. convert each measurement to the unit specified.

a. 25 cm = ______________ mm
b. 300 ml = ______________ l
c. 35 kg = ______________ mg
d. 5.6 km = ______________ m
e. 13500 mm = ______________ m

1. complete the following chart:

item to be measured	personal reference	reasoning	estimate
height of the teachers desk
mass of a chair

Explanation:

Step1: Recall length - unit conversion

1 cm = 10 mm, so for 25 cm, we multiply by 10. $25\times10 = 250$ mm.

Step2: Recall volume - unit conversion

1 L = 1000 mL, so for 300 mL, we divide by 1000. $300\div1000=0.3$ L.

Step3: Recall mass - unit conversion

1 kg = 1000000 mg, so for 35 kg, we multiply by 1000000. $35\times1000000 = 35000000$ mg.

Step4: Recall length - unit conversion

1 km = 1000 m, so for 5.6 km, we multiply by 1000. $5.6\times1000 = 5600$ m.

Step5: Recall length - unit conversion

1 m = 1000 mm, so for 13500 mm, we divide by 1000. $13500\div1000 = 13.5$ m.

Answer:

a. 250
b. 0.3
c. 35000000
d. 5600
e. 13.5
