Bryan used 1/7 of his savings to buy a book. He spent 1/2 of the remaining money he had on a bag. What fraction of his savings was left?
Assume the total to be a fraction out of 1.
Let's see how much he spent in total first:
1/7 + 1/2 = 2 + 7/14
Now we can find what was left.
We can assume the 1 whole to be 14/14 to be the calculation 100 times easier.
14/14 - 9/14 = 5/14
And that is how much of his savings are left.
