Answer:
He is correct
Step-by-step explanation:
multiplication and division are inverse operations so lets divide to see if he is correct
40.7/10=4.07
he is correct
Since the result tallies with Ethan's assumption, hence the result of Ethan is correct.
According to Ethan, he assumed that the product of 10 and 4.07 is 40.7, we are to check if the calculation of Ethan is correct.
To do that, we will have to multiply 10 with 4.07 as shown below:
[tex]= 10 \times 4.07 \\= 10 \times \frac{407}{100}\\=\frac{4070}{100} \\=40.70[/tex]
Since the result tallies with Ethan's assumption, hence the result of Ethan is correct.
