Question

Simplify (2/5+3/2)÷3/10 as a rational number and show that it is between 6 and 7

Answer 1

Answer:

(2/5 + 3/2) ÷ 3/10 = 6.34 which lies between 6 and 7

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
