Answer:
5/6
Explanation:
so for the first equation I would keep 1/3 the same
flip the division sign to multiplication
and turn the second fraction 4/10 upside down so it becomes 10/4
10/12 can be simplified by dividing 2 on the numerator and denominator
10/2=5
12/2=6
5/6
for the second equation I know that each number in the first equation should be present in the second(since they are all the same numbers). However, 5/6 is not present in the second equation so that is the missing number
Hope this helps!
