Question

plzzzz anybody how now

Answer 1

If
( 3 / 5 + 3 / 10 ) + 7/ 15 = ( 7 / 15 + 3 /10 ) + 3/5
then the given no.. will follow associative property
LHS ...( 3 / 5 + 3 / 10 ) + 7 / 15
(6 + 3 / 10 ) + 7/15
9 / 10 + 7 / 15
9 × 3 + 7 × 2 / 30
27 + 14 / 30
41 / 30
Now
RHS... (7/15 + 3/10) + 3/5
(7 × 2 + 3×3) /30 +3/5
(14 + 9 /30) + 3/5
23 / 30 + 3 /5
23 +( 3 × 6) / 30
23 + 18 / 30
41 / 30
so LHS = RHS...
