If you make the numbers into a ratio, it'll be easier to find the answer. There are 68 blue squares for the 4 green squares in the quilt. 68:4, or 68/4 If we do the division of the ratio, 68/4, we end up with 17. Now, we multiply that by the 11 green squares of the new quilt. 17x11=187 This shows that there will be 187 blue squares in the quilt with 11 green squares.
