Hi Nafis!

Here are two ways of thinking about it:

1) Imagine 3/8 as 3/8 of a pizza. Pizzas usually are broken into 8 slices, so 3/8 of a pizza is 3 slices. Similarly, 3/4 of a pizza is (think about it) 6 slices. So the problem is basically:

3 slices minus 6 slices

But you only have 3 slices to give! So if you try to minus more than you have to give, you owe slices. In this case, if you have 3 slices and you minus 6, you give all your slices away and still end up owing 3 slices. That's -3 slices. But slices are parts of a pizza so the answer is -3/8

2) 3/8 - 3/4 . Find a *common denominator* --> in this case, 8. Convert the 3/4 into an equal fraction with an 8 in the denominator by multiplying both numerator and denominator by 2. Then the problem becomes:

3/8 - 6/8

Then, since 3 - 6 = -3, combine the numerators and you get:

-3/8

I hope at least one of those was helpful to you! :)
