Answer:

6/7 - 1/3

Step-by-step explanation:

You know that 1/2=0,5

Then, you have to solve the two sums:

[tex]2/15+1/3=((2*3)+(15*1))/(15*3)=(6+15)/45=21/45=0,4666=0,47[/tex]

[tex]6/7-1/3=((6*3)-(7*1))/(7*3)=(18-7)/21=11/21=0,5238=0,52[/tex]

You now know what number of 0,47 and 0,52 is closer to 0,5; which is 0,52

0,47 is to 0,03 from 0,5

0,52 is to 0,02 from 0,5
