2/5 * (-3)/7 - 1/6 * 3/2 +1/14 *2/5

plz... plz... answer it..

2/5 X  (-3)/7 - 1/6 X 3/2 + 1/14 X 2/5

= {2/5 X  (-3)/7} - (1/6 X 3/2) + (1/14 X 2/5)

= (-6)/35 - 1/4 + 1/35

= {(-24) - 35 + 4}/140

= (-55)/140

2/5 * (-3)/7 - 1/6 * 3/2 +1/14 *2/5

 

= 2/5 X (-3)/7 -1/6 X3/2 +1/14 X 2/5 = 2/5 X (-3)/7 + 1/14 X 2/5 -1/6 X 3/2 (By commmutative property)

= 2/5 X [-3/7 +1/14] - 1/4 (By distributive property)

= 2/5 X [-5/14] -1/4

= -1/7 - 1/4

= (-4 -7)/28

= -11/28

2/5 * (-3)/7 - 1/6 * 3/2 +1/14 *2/5

 

= 2/5 X (-3)/7 -1/6 X3/2 +1/14 X 2/5 = 2/5 X (-3)/7 + 1/14 X 2/5 -1/6 X 3/2 (By commmutative property)

= 2/5 X [-3/7 +1/14] - 1/4 (By distributive property)

= 2/5 X [-5/14] -1/4

= -1/7 - 1/4

= (-4 -7)/28

= -11/28

therefore your required answer is -11/28
