Emma is preparing a spice mix. She needs 4 $$\frac{3}{5}$$ teaspoons of paprika. She needs 2 $$\frac{1}{5}$$ teaspoons of black pepper. Emma calculates how much more paprika than black pepper she needs. 4 $$\frac{3}{5}$$ − 2 $$\frac{1}{5}$$ = $$\frac{23}{5}$$ − $$\frac{11}{5}$$ = $$\frac{12}{5}$$ = 2 $$\frac{2}{5}$$ Is Emma correct?

Emma is correct because she rewrote each mixed number as a fraction greater than one

Emma is incorrect because she only wrote the whole numbers as fractions greater than one

Emma is correct because she only subtracted the numerators and not the denominators
