Help: Solve it step by step (Answer is 33/70)
​

Answer 1

$\frac{ - 2}{5} - \frac{ - 4}{7} - \frac{ - 3}{10}$

$\frac{ (- 2 \times 70) - ( - 4 \times 50) - ( - 3 \times 35)}{350}$

$\frac{ - 140 - ( - 200) - ( - 105) }{350}$

$\frac{ - 140 + 200 + 105 }{350}$

$\frac{- 140 + 305 }{350}$

$\frac{165}{350}$

$\frac{33}{70}$

10

−3

(−2×70)−(−4×50)−(−3×35)

{ - 140 - ( - 200) - ( - 105) }{350}

350

−140−(−200)−(−105)

{ - 140 + 200 + 105 }{350}

350

−140+200+105

{- 140 + 305 }{350}

350

−140+305

{165}{350}

350

165

{33}{70}
