Question

find 2 by 5 into bracket minus 3 by 7 close bracket minus 10 by 6 into 3 by 2 + 10 by 4 into 2 by 5

Answer 1

[2/5x(-3/7)]-[10/6x3/2]+[10/4x2/5]= -6/35-5/2+1= -12-175+1/70= -117/70

Answer 2

Solution:-

$\frac{2}{5} \times ( - \frac{3}{7} ) - \frac{10}{6} \times \frac{3}{2} + \frac{10}{4 } \times \frac{2}{5} \\ \frac{ - 6}{35} - \frac{30}{12} + \frac{20}{20} \\ \frac{ - 72 - 1050 + 420}{420} \\ \frac{ - 705}{420} \\ \frac{ - 141}{85}$
