The mistake that Josue made is Choice C:
93 hundredths is 0.93, not 9.39.
The mistake that Josue made is in Step 2. The correct calculation should be 186 hundredths divided by 2, which equals 93 hundredths. So, the correct answer is Choice B: 186 hundredths ÷ 2 is 43 hundredths, not 93 hundredths.
Choice A: This is not the mistake Josue made. Josue correctly wrote 1.86 as 186 hundredths before dividing by 2.
Choice B: This is the mistake Josue made. When dividing 186 hundredths by 2, the correct answer is 93 hundredths, not 43 hundredths as Josue wrote in step 2.
Choice C: This is not the mistake Josue made. After correctly dividing 186 hundredths by 2 to get 93 hundredths, Josue incorrectly wrote 9.3 instead of 0.93.
Therefore, the correct answer is (Choice B) 186 hundredths ÷ 2 is 93 hundredths, not 43 hundredths.
