Question

Jadyn and Leah were in a fishing tournament. Jadyn's fish weighed 2.120 kilograms. Leah's fish weighed 2.12 kilograms.

Jadyn says his fish weighs more because 120 is larger than 12. Is he correct? Explain your answer. Use place value to support your thinking.

Answer 1

Answer 2

Jadyn is wrong

Given:

Jadyn's fish weighed 2.120 kilograms.

Leah's fish weighed 2.12 kilograms.

Jadyn says his fish weighs more because 120 is larger than 12.

To find:  

Is Jadyn's thinking is correct

Solution:  

Given Jadyn's fish weighed 2.120 kilograms

Leah's fish weighed 2.12 kilograms.

If we convert given weights into grams

2.120 kg  = 2.120 × 1000 = 2,120 grams

2.12 kg = 2.12 × 1000 = 2,120 grams  

So here we can clearly see that

2.120 kg = 2.12 kg  

Here we can conclude that after a decimal point value of 0 at end value is nothing like 0.3 and 0.30 are equal

If we represent both given numbers in place value chart

Place value:   Hundred  Ten  one  Tenths  Hundredth  Thousandth  

        2.120 :           -          -         2         1               2                   0

         2.12 :           -          -         2         1               2                   -

Here  2.120Kg = 2.12 kg  

Jadyn is wrong
