Nw let's take a simple example.
2(3-2)
Let's first remove the bracket to solve this.
2(3-2)=2*3-2*2.
Removing the brackets means to multiply the terms inside the bracket by the one outside. See if that makes a little sense

Say u need to multiply 2/3 by 5.
First multiply 2 by 5. U vl get 10.
Nw divide 10/3. See if u get a whole number if u do divide. If so write t. If nt leave the fraction as it is. See if that makes a little sense.
