How many 's 1/10 of a whole pie are there in 4/5 of a whole pie?

Answer 1

There are ten 1/10s in one whole pie, and 5 1/5 in one whole pie. That means there are two 1/10s for every 1/5 of the pie. Since you're dealing with 4/5, you multiply 2 times 4, and you get 8. There are 8 1/10s in 4/5 of a whole pie.
