How many centigrams are there in 24 grams?
a.
Restate the question: 24 grams
=
centigrams
b.
Use the place value chart to determine the multiplication factor, and solve:
kilo
hecto
deka
meter, liter, or gram
deci
centi
milli
thousands
hundreds
tens
ones
tenths
hundredths
thousandths
Since we want to convert grams (ones place) to centigrams
(hundredths place), count the number of places on the chart
it takes to move from the ones place to get to the hundredths
place. Since it takes 2 moves to the right, the multiplication
factor is 100.
Solution: multiply 24 x 100
=
2,400.
Answer: There are 2,400 centigrams in 24 grams.

Use the place value chart to determine the multiplication factor, and solve:
Since we want to convert deciliters (tenths place) to liters (ones
place), count the number of places on the chart it takes to move
from the ones place to get to the hundredths place. Since it
takes 1 move to the left, the multiplication factor is 0.1.
Solution: multiply 5,000 x 0.1
=
500.
