Question

verify 2/5×(4/9×3/1)=(2/5×4/9)×3/1​

Answer 1

Answer:

hi

your answer is here !

Step-by-step explanation:

LHS = (-2/5 +4/9) + (-3/4)

={(-2)×9 + 4×5}/45 + (-3/4)

={-18+20}/45 + (-3/4)

=2/45 + (-3/4)

=2/45 -3/4

=(2×4-3×45)/180

=(8-135)/180

=(-127)/180

RHS =-2/5 + { 4/9 + (-3/4)}

= -2/5 + 4/9 -3/4

=-(2/5 +3/4) +4/9

= -{2×4+5×3}/20 + 4/9

= -(8+15)/20 + 4/9

= -23/20 + 4/9

=4/9 -23/20

=(4×20-23×9)/180

=(80-207)/180

=(-127)/180

we see LHS = RHS

so, varified that this is correct .
