This problem deals with the order of operations which is.
1) Parenthesis
2) Exponents
3) Multiplication & division from left to right
4) Addition & subtraction from left to right
So we will evaluate each expression using the above rules
A. 8+24 divided by(12x4)
8+24 ÷ (12x4) The (12x4) must be done first as parenthesis operations happen before others
8+24 ÷ (48) The 12 ÷ 48 happens next. (Multiplication or division from left to right)
8+1/2 Finally, we add 8 and 1/2
8 1/2
So this is not equal to 2/3
B. 8+(24 divided by 12)x4 First we do the parenthesis (24/2)
=8+(2)x4 Next it's multiplication or division from left to right
=8+8 Finally we add 8+8
= 16 (This is not equal to 2/3)
C. (8+24) divided by(12x4) First we do the parenthesis (8+24) and (12x4)
32/48 Next we simplify the fraction by finding the greates factor that goes into the numerator and denominator. In this case, that greatest common factor is 16
= 2/3 This is the answer we are looking for.
D. 8+24 divided by 12x4 Since there are no parenthesis, we do multiplication and division from left to right
8+2x4 again.. Multiplication
8+8 Finally we can add 8+8
=16 This is not the answer we are looking for.
So C has the value of 2/3
