1) find the relation between cm and m

1 meter = 100 cm

So divide 4250 by 100

4250/100 = 85/2

So there are 85/2 meters


2) now use the relation between m and km

1 km = 1000m

So:

35.25 / 1000 so the answer is c1


3) same as before

1 meter = 100 cm

78.5 m = 78.5 * 100 cm
It's equal to the relation because you're multiplying both sides by 78.5

So then 78.5 * 100 = 7850 cm


4) this one you just subtract:

Manny = 562.5
Brother = Manny - 75

Plug in:
562.5 - 75 = 487.5


5) first find the difference in grams

1,850,000 - 1,525,000 = 325,500

Now 1kg = 1000 g

So 325,500 / 1000 = 325 kg
