posted by .

A set of building blocks includes squares of various shapes and colors. If 20% of the blockers were square and 50% of the squares block are red, then ___ of the blocks are red squares.

My answer is 40% (20% x 50% / 100% = 40%). Is this correct?

    No. Consider you have 100 blocks.
    20 are square.
    10 of the square are red.
    That is ten percent of the blocks are red squares.

    check my thinking.
