hence proved
Step-by-step explanation:
given: (2/5 + 3/2) ÷ 3/10
to prove : the resultant is between 6 and 7
simplification:
2/5 + 3/2 (taking 10 as L.C.M )
= 4+15/10
= 19/10
(2/5 + 3/2) ÷ 3/10
= 19/10 ÷ 3/10 (reciprocation)
=19/10 × 10/3
(cancellation of 10)
= 19× 1/3
=19÷3
= 6.3333.....
=6.34 which lies between 6 and 7
hence proved
