    Answer:

    10+8+6=24 the ratio of taking the biographies to the science books are: 4:3

    Step-by-step explanation:

    That is the answer because 10+8+6= total 24 books

    ratio of biographies= 24:8=3:1

    ratio of science fiction= 24:6= 4:1

    hence according axiom 1 ab × Ac= aa × BC

    3:1×4:1= 4:3
