Question

One senenth of string was used to support a pole and 3/5 of the reminder was used to tie of a parcel,what fraction of the rope remained?

Answer 1

Use the information that you have so far:

1/7 , 3/5

add this to find out how much has been used (add the fractions):

1/7+3/5 = (1/7)*5 +(3/5)*7 = (5+21)/35 = 26/35

now find out how much is left. Subtract the whole (1 or 35/35) by what has been used (26/35):

35/35 - 26/35 = 9/35

I hope this helps.
