How do you simplify #3/4+(1/4-1/6)#?
First we must find common denominators.
4 and 6 are not the same number, so we need to find the lowest common number that they both go into. 24 is the lowest number that they both fit into. So, we must multiply these fractions by
Next it is a matter of PEMDAS, or specific order of operations. PEMDAS states that we must first solve what is inside the parentheses before we can do the outsides.
And now we can do the addition outside the parentheses.
All there is left to do is simplify. Both 20 and 24 are divisible by 4.
