Answer:
The ratio of 1 by 5 is to 1 by 6 is Rs 176 : Rs 146.67
Step-by-step explanation:
The given amount here = Rs 880
Now let us assume the 1 by 5 of Rs 880 = m
and assume 1 by 6 of the amount Rs 880 =n
To Find m : n
Now, 
or, 1 by 5 = 176
Similarly: 
or, 1 by 6 = 146.67
⇒ m : n = 176 : 146.67
Hence, the ratio of 1 by 5 is to 1 by 6 = Rs 176 : Rs 146.67
