Given that:- two sisters eat the same number of gluten-free rice cakes
Susanna eats rice cake=4/5
Melanie eats rice cake=⅔
How many rice cakes do they eat in one day=?
they both eat rice cake in one day = susanna eat in one day + melanie eat in one day
=4/5+⅔ (LCM of 5 and 3 is 15)
=12/15+10/15
=22/15 = 1 7/15 (Answer)
