Hey, it's been a while since I've had to care about mixed numbers. In college larger numerators are considered the norm.
I think you just do the division in your calculator. You should get 14.9285714285714286
Take the whole number (14) and separate if from the decimal. Then find the new fraction for the decimal (0.9286...) There probably isn't a fraction for this. So I would shorten it to two decimals (.92) and take your fraction from that
Your mixed number will be 14 and 92/100
