# Fast Math - Randomized Fraction Addition

In this quiz the answers change every time you play! Solve these randomised addition of fractions problems as fast as you can!

FORMAT: JetPunk only recognises A-Z and 0-9, so you can't input fractions directly. Simply input TOP followed by BOTTOM in the fraction's simplest form. I.e. if the answer is 3/6, simplify to 1/2 and type either "12", "1 2", "1/2" etc...
Answer must correspond to highlighted box!

Great! There was a mistake in one of my questions: 1/12 + 9/11 =55/61

I fixed it! Turns out the format for Fractions in excel was defaulting to two digit numbers as the Numerator and Denominator, thus anything with 3 digits would be rounded up or down. Hence the answer was adjusted slightly.

All fixed now though! Thanks for pointing it out :)

if you think this is hard, use this formula :

(a / b) + (c / d) = (ad + bc) / bd

You should use 1 instead of 1/1.

The inproper fractions should be change into mixed fractions: 9/8 can be 1 1/8.
