You must show your working and state clearly whether the answer is A or B.

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 .

the ratio of white tiles to blue tiles is 48: 16. the ratio in it's simplest form is 3: 1.

step-by-step explanation:

ratio: take the first number and add a colon next to it, then add the second number after that. make sure the ratio order matches up with the written problem!

simplest form: we can simplify the ratio 48 : 16 by dividing both terms by the greatest common factor (gcf).

the gcf of 48 and 16 is 16.

divide both terms by 16:

48 ÷ 16 = 3

16 ÷ 16 = 1

reducing to simplest form:

48 : 16 = 3 : 1

18

step-by-step explanation:

draw the shape and you will see that f and k are actually at adjacent vertices (points of the hexagon that are neighboring).   so find the distance between (1,2) and (4,2).   that is easy since (1,2) and (4,2) is just a vertical distance to count, which is 3.   it is a regular polygon which means all sides are congruent.   you have 6 sides (hexa) so multiply 6 by 3 to receive 18.
