A girl spent 1/4 of her pocket money on Monday and 3/8 on Tuesday , What is the fraction of her pocket money is left

1 - 2/8 - 3/8 = 5/8

oops. 1 - 5/8 = 3/8

To find out what fraction of her pocket money is left, you need to subtract the fractions she spent from the whole amount.

First, let's determine the common denominator for 1/4 and 3/8. The smallest number that both 4 and 8 can divide evenly into is 8.

Next, we can convert 1/4 and 3/8 to have the same denominator of 8.

1/4 becomes 2/8 since multiplying the numerator and denominator by 2 gives us the equivalent fraction with denominator 8.

3/8 remains as 3/8.

Now we can subtract:
2/8 - 3/8 = -1/8

The result is negative, which implies that she spent more than she had.

Thus, after Monday and Tuesday, she overspent by 1/8 of her pocket money.
