Answer:
12 is the correct answer
Step-by-step explanation:
1) so whenever we're dividing with fractions we need to change the division sign to multiplication and turn the second fraction upside down (reciprocal)
so
6*2/1=12
Julio did change the division sign to multiplication but he forgot to take the reciprocal of the second fraction (he left the second fraction as is)
what Julio did: 6*1/2=3
Hope this helps!
