plz mark as brainliest

Step-by-step explanation:

i) (2/5×5/8) + (-3/7×14/-15)

= lcm of denominators = 40 and other is -105

= 2×8 = 16 + -3 × -15 =45

5×8=40 7× -15 =-105

= 16/40 + 45/-105

= lcm of denominators = -4200

= 16× -105 = -1680 + 45×40= 1800

40×-105 = -4200 -105×40= -4200

= -1680/-4200 + 1800/-4200

= 120/-4200 or in simplest form

= 1/-35

do the others like this
