All you need to do for this is 155-75 which would be 80 :) hope this helps
Answer:
7 1/2
Step-by-step explanation:
A water tank contains 12 1/2 liters
= 25/2
Two fifth of it was consumedd
= 25/2 ×2/5
= 50/10
= 5
12.5-5
= 7.5
= 7 1/2
56.347..........
just simply put the value 3175 under division root and make pairs of 31 and 75.Now think of a number whose square will be nearest to 31 and that ll be 5.Now write 5 in the quotient and 5 also 5 under the divider.Now by multiplying 5 with the 5 in the quotient you ll get 25 write this under 31.And by adding 5 in the divider 5 youll get 10.write this under the divider.no by subtracting 25 from 31 you ll get 6 and by bringing 75 down it ll be 675.Now think of a number again and write it with 10.Like 6 into 6 is 36 and when you multiply 6 with 106 you ll get nearest number to 675 that ll be 636.Now because its giving a remainder just add a .0 in the question and continue to solve it the same way.And as it ll be a continuous answer so just add continuty dots........ or just round it off to nearest whole number
