Question

(iii) {(-9)/5 X (-10)/3} x 21/-4 = (-9)/5 * {(-10)/3 x 21/-4}
(iv) 3/7 * {5/6 + 12/13} = (3/7 * 5/6) + (3/7 x 12/13)
(v) -15/4 * (3/7 + (-12)/5) = (-15/4 * 3/7) + (-15/4 * (-12)/5)
(vi) (-8/3 + -13/12) x 5/6 = (-8/3 x 5/6) +(-13/12 x 5/6)
(vii) -16/7 {-8/9 + (-7)/6} = (-16/7 x (-8)/9) + ((-16)/7 * -7/6)​
