    you can cross multiply which is -8*1 over 4*7

    then simplify which will give (-2*1)/(1*7) = -2/7

    Yeah cross multiply was a poor choice of words, when you have two fractions you want to multiply, you multiple the numerators and denominators together, then simplify if you can

    meaning -8/7*4/1 =32/7

    yes that would be correct but you had the original equation as -8/7 *1/4= -8/28 = -2/7

    Not when you are simply multiply to fractions together, it would be the numerator times the numerator, and the denominator times the denominator.
