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.

When Sharmi compared 37.09 and 37.7, by adding that 0 in the tenths place she changed the value completely. 37.07 is not the same as 37.7. 37.07 is less than 37.09 but 37.7 is equal to 37.70 so therefore you would be comparing 70, and 9. not 7 and 9. So basically Sharmi put the 0 in the wrong digit place. Confusing the number 37.07 and 37.7(37.70)
