we need to know how many squares there are in total, and then how many are shaded, then we can calculate it
OpenStudy (adajiamcneal):
4 shaded and 16 unshaded.
OpenStudy (amistre64):
its an 8x8 grid, how many squares in total is it?
OpenStudy (adajiamcneal):
64
OpenStudy (amistre64):
then since 4 out of 64 are shaded
that leaves 60 out of 64 not shaded, what is 60/64?
