You want to turn them into improper fractions:
81/16/31/8
Flip over the 31/8 fraction:
81/16*8/31
Cancel out the 8 and 16:
81/2*1/31=81/62=
1 19/62 or 1.3064

5 1/16 = 81/16
3 7/8 = 31/8
81/16 divided by 31/8
(81/16) * (8/31)
(81*8)/(16*31) = 648/496 = 81/62
= 1 19/62

Your first step would be to convert both of those mixed fractions into improper fractions.
To get the number on the top, multiply denominator by whole number, then add numerator. To get the number on the bottom, just keep the existing bottom.
Therefore, 5 1/16 converts to 16 times 5, plus 1, over 16 OR
81/16
Similarly, 3 7/8 converts to 8 times 3, plus 7, over 8, OR
31/8
So you want to calculate
81/16 divided by 31/8
Remember that dividing fractions is exactly the same as multiplying by the second fraction's reciprocal. Thus
81/16 times 8/13
At this point, you just multiply normally. Keep in mind that the 8 and 16 have a GCF and can be reduced to 1 and 2 respectively. The final answer should be
81/26
