so PEMDAS
the order of simplification/operation is
parenthaseese
exponents
multiplication or division whichever comes first
addition or subtraction whichever comes first
so we work the parenthasees inside to out
inside parenthaseese=(10-4/2)
so no exponents so skip
there's division so we do that
4/2=2/1=2
then we have
(10-2)
subtraction
10-2=8
(8)
next parenthaseese/bracket
[5 times (8)+15]
multiplication
5 times 8=40
[40]
other brackets
{390-[40]+15}
subtraction
390-40=350
{350+15}
350+15=365
outside
2 times {365} times 2
multiplication
2 times 365=730
730 times 2=1460

your answer is -542,340
2 * {390 - [ 5 *( 10 - 4 / 2)] + 15} * 2.
2*{390-[5*(8)]+15}*2
2*{390-[40]+15}*2
2*{390[-40]+15}*2
2* {-135,585}*2
{-271170}*2
-542,340
2 * {390 - [ 5 *( 10 - 4 / 2)] + 15} * 2.
2*{390-[5*(8)]+15}*2
2*{390-[40]+15}*2
2*{390[-40]+15}*2
2* {-135,585}*2

To divide fractions, we do Keep, Change, Flip. Keep means that we keep the first fraction the same ( which is 8/1). Then for Change, we change the division sign to a multiplication sign. After that we Flip the second fraction itś reciprocal (or multiplicative inverse).
So your equation would be:
8/1 x 3/1 which equals 24
So your equation would be:
8/1 x 3/1 which equals 24

2/8 = 3/12 is a porportion.
To find out, simplify each of the fractions.
(2/8)/(2/2) = 1/4
(3/12)/(3/3) = 1/4
2/8 = 3/12 is your answer
hope this helps

the equivalent fraction would be 2/4. as you can see, 2/4 can be simplified down to 1/2. if you filled up half of the fraction bar, you would have 2 boxes of 1/4 filled. 1/4 and 1/4 is 2/4
