Hi Mike, if I grid in an answer like 30/4, would it be counted wrong because it wasn’t fully simplified to 15/2? Thanks!

Good question. You do NOT have to reduce fractions when you grid in. So in your example, 30/4, 15/2, or 7.5 would all be acceptable answers. Note that if your fraction is so big that it doesn’t fit in the 4 spaces you have, then you’d need to reduce. For example, “8/100” should be reduced because it won’t fit in the 4 spaces.
