If Samriti travels 7/12 of her trip she has 5/12 remaining.
Her total trip will be 12/12 therefore if you find what you need to add to 7 to make five we find the remainder of her journey. 12-7=5
If her total trip is 240 miles and we need to find 5/12 of it.
We first divide it by 12: 240/12= 20
This gives us 1/12 of her trip, 20=1/12
We now need to multiply 20 by 5 so get 5/12 of her trip:
5 x 20 =100
Therefore, 100 is the same as 5/12, which is the remainder of her journey.
