Question

find the value of 2/9-(4/5-7/15) and (2/9-4/5)-7/15. are the two results equal​

Answer 1

Answer:

Half of the number is 315.

415×57×n=(49×25×n)+8

⟹45(20n105)=45(8n45+8)

⟹7(60n7)=7(8n+360)

⟹60n−56n=(56n+2520)−56n

⟹4n8=25208

n2=315

Proof:

415×57×630=(49×25×630)+8

⟹4×5×6=(4×2×14)+8

⟹120=112+8

⟶120=120

Answer 2

Answer:

no they are not equal

LHS = -8/45 WHILE RHS =-47/45

Step-by-step explanation:

2/9-(4/5-7/15)

by taking LCM

2/9-(13-7/15)

=2/9-(6/15)

2/9-(2/5)

=2/9-2/5

by taking lcm

10-18/45

= -8/45 ans (lhs)

RHS

BY TAKING LCM

(10-36/45)-7/15

=(-26/45)-7/15

= -26/45-7/15

by taking LCM

-26-21/45

= -47/45 answer
