c. 3/6
d. 3/4

Answers:
Parenthesis are used to indicate to do the math that is within them before doing what is outside them. Since there is nothing outside they serve no purpose and should just be ignored.

4/6 - 1/2 = 4/6 - 3/6 = 1/6 = 2/12
isnt it d?
c
1/2 can be changed to 3/6 so 4/6 -3/6 would be 1/6 the parenthesis dont matter int his equation
and 2/12 simplified is 1/6 so the answer is a
A 2/12
A :)
a. but that would have to be reduced to 1/6
okay well 1/2 is the same as 3/6

so the question is really asking 4/6 - 3/6

that equals 1/6 which is equivalent to 2/12
its (a)

4/6 - 1/2 = 4/6 - 3/6 = 1/6

now from your choices, you can see that 1/6 = 2/12
(1/6 * 2/2 = 2/12)


so it's a
4/6 - 1/2
4/6 - 3/6
1/6 = 2/12 --> a
4/6 - 1/2
=4/6 - 3/6
=1/6
=2/12

Ignore the brackets. They don't mean anything when they're around the whole equation. The answer is a) 2/12.
