Question

In an office,2/3 of the telephone bill is paid by Tom,1/5 paid by Azuma and the remaining by Tina. What fraction is paid by Tina?​

Answer 1

Answer:

4/15

Step-by-step explanation:

1 - 2/3 = 1/3

1/5 x 1/3 = 1/15 of the bill

1/15 of bill is paid by azuma

10/15 is by tom

so 1 - 10/15 - 1/15 = 4/15 by tina

Answer 2

I am 99% sure that the correct answer is: 2/15. 2/15 of the bill is paid by Tina.
2/3 Tom (2•5/3•5.=10/15)
1/5 Azuma (1•3/5•3=3/15)
10+3+x=15
x=15-13
x=2

To make everyone’s share 1 or 100%, we have to make Tina’s share into a fraction is denominator of 15, making it to: 2/15
