Step-by-step explanation:
___ x 1 5/6 = 9 1/6
To find the missing fraction, we need to divide 9 1/6 by 1 5/6.
First, convert the mixed fractions into improper fractions.
9 1/6 = ((9*6)+1)/6 = 55/6
1 5/6 = ((1*6)+5)/6 = 11/6
55/6 ÷ 11/6 ⇒ 55/6 * 6/11 = 55*6 / 6*11 = 55/11 = 5
The missing number is 5.
5 * 1 5/6 = 9 1/6
5 * 11/6 = 9 1/6
55/6 = 9 1/6
9 1/6 = 9 1/6
