Alexis bake 90 pizzas each pizza is cut either into 8 small slices or 6 slices. Alexis has 5 small slices for every 3 large slices. How many of the 90 pizzas are cut into small slices?

there's about 22 because if you extend it by going 3+1 and so on it wont hit 90 exactly but it'll be 91, so 22 small sliced pizzas and 23 large sliced pizzas
