Question

Sharmi compared thirty-seven point zero nine and thirty-seven point seven and provided the explanation below. Explain what she did wrong and provide the correct solution and explanation.

In thirty-seven point zero nine, the final digit is a 9. For thirty-seven point seven, since there were fewer digits, Sharmi filled in the tenths place value with a zero to get thirty-seven point zero seven. Here, the final digit is a 7. Since 9 is greater than 7, the correct answer is greater than or equal to.
