The answer is B

Step-by-step explanation:

A:

2/15 + 1/3

= 2/15 + 5/15

= 7/15

= 0.47 (2d.p)

B:

6/7 - 1/3

= 18/21 - 7/21

= 11/21

= 0.52(2d.p)

1/2 = 0.5

So B is closer to 0.5

B is closer to .

Step-by-step explanation:

Given,

A⇒

B⇒

To find which is closer to

Now,

=

= = 0.4666= 0.47

=

= = 0.523

= 0.5

B is closer to .
