Unit 3 lesson 4: Converting Units

Unit 3 lesson 4: Converting Units

Multiple Choice

DO NOW: Predict which is heavier 1 kilogram or 1 pound?

• 1 POUND

• 1 KILOGRAM

We had to think about the ratio of Kilograms to Pounds

• For every 1 kilogram there is 2.2 pounds

• 1:2.2 is the ratio

• Using a double number line, ratio table, or thinking about "for each, per" we can find the pounds in any change in kilograms through MULTIPLICATION AND DIVISION

FOR EXAMPLE:

2 KILOGRAMS HAS 4.4 POUNDS

BECAUSE

1:2.2 IS THE RATIO FOR 1 KILOGRAM. FINDING FOR 2 KILOGRAMS

TO GET TO 2:4.4 WE MULTIPLY BOTH SIDES OF 1:2.2 BY 2

PSSST. THERE IS A COOKIE POINT HERE!

Multiple Choice

How many pounds are in 8 kilograms knowing there is 1 kilogram for every 2.2 pounds.

• 17.6 pounds because we have to multiply 8 on both sides to get 8 kilograms and 17.6 pounds

• 2.2 pounds because we multiply 1 kilogram by 8

Ms. Kuqi is on the MOON!

• On earth Ms. Kuqi weighs 165 pounds but on the moon she weighs 0.45 pounds on the MOON!

• How many kilograms does Ms. Kuqi weigh on Earth?

• How many Kilograms does Ms. Kuqi weigh on the MOON?

Multiple Choice

There is 1 kilogram for 2.2 pounds. If Ms. Kuqi weight 165 pounds on earth how many kilograms is that?

• 75 kilograms

• 50 kilograms

75 kilograms!

1) We can figure out how many kilograms for 1 pound by dividing by 2.2 on both sides.

2) We get 0.45 kilograms in 1 pound.

3) Then we can multiply by 165 to figure out that there are 75 kilograms in 165 pounds.
