=(- 3 / 2) × 3 / 4 × (- 0.05) × (- 7 / 4). (becomes false fraction)
=(- 3 / 2) × 4 / 3 ÷ (- 0.05) × (- 7 / 4). (reverse multiplication)
=(- 2) / (- 0.05) × (- 7 / 4) (- 2) / (- 0.05) × (- 7 / 4)
=2 △ 0.05 × (- 7 / 4). (first term divided by second term)
= 0.1 × ( - 7 / 4 )
= - 1 / 10 × 7 / 4
= - 7 / 40
