Question

Luke measured caterpillars for a science project. He believes that caterpillar A is longer than caterpillar B because it has more digits after the decimal point. Do you agree or disagree Luke's thinking. Explain your reasoning.

Caterpillar A=4.125 cm
Caterpillar B=4.03
Caterpillar C=4.23

Answer 1

Answer: disagree

Explanation:

Caterpillar A is longer, but not because of the decimal places. It is longer because of the place value.

Answer 2

Disagreed

Explanation:

In order to find the answer to this question you must remember that when dealing with finding the greater decimals you have to look at which have the greater place values in this case...

`CA=4.125`

`CB=4.03`

`CC = 4.23`

Caterpillars 1 place value is already greater then caterpillar B's place value of 0, so it doesn't really matter how many more numbers to add after 1 and 0 because these two place values are already different 1 > 0

Meaning that "although Caterpillar A is greater then Caterpillar B, it is not because it has more digits simply because one is greater then zero." You can prove this by seeing that Caterpillar C is greater then Caterpillar A because two is greater then one.

`4.125 > 4.03`

`4.125 < 4.23`

Hope this helps.
