@princesstwilight If 2/9 of 3/8 are metamorphic, that is 1/12 of the whole. This is equal to 8/96. The portion that is igneous is 60/96. This means the remaining (sedimentary) portion is 28/96. If there are 48 more igneous than sedimentary rocks, 48 = 32/96. Seeing as this is one third of the whole, the total amount of rocks is 48 x 3 = 144. Pinkie would have to throw 144 individual parties if each rock has an individual birthday.
