Which number sentence will tell how long Maria’s driveway is, measured in kilometers?

A.
35.25 × 100

B.
35.25 ÷ 1,000

C.
35.25 ÷ 100

D.
35.25 × 1,000

The mass of a large adult male hippo is about 1,850,000 grams and the mass of a large adult female is about 1,525,000 grams.

What is the difference, in kilograms, between the masses of the adult male and female hippos?

So we want to know how long Maria's driveway is in kilometers if we know the length in meters. L=35.25m. To get the length in kilometers we need to divide the length by 1000 and so the length L= 0.3525km. And we want to know the difference in mass in kilograms between an adult male and female hippo. Mm=1850000 g = 1850 kg, Mf=1525000g=1525kg. Mm-Mf=325kg and that is the mass difference in kilograms.
