To get the difference between recipes we have to subtract 31/4 - 23/4. When we are subtracting fraction we have to have common denominator - its ok here. Now subtraction will be easy, only subtract numerator, denominator will not change.
[tex] \frac{31}{4}- \frac{23}{4}= \frac{31-23}{4}= \frac{8}{4}=2 [/tex] - its the result, so in bead recipe is 2 cups more than in muffin.
To get total cups required to cook bread and muffin we have to add 31/4 and 23/4. Its very similar to subtraction.
[tex] \frac{31}{4}+ \frac{23}{4}= \frac{31+23}{4}= \frac{54}{4} =13.5 [/tex] - the result is 13.5 cups.
