Make bottom numbers same find least common multipules of 8,12,4 and 3 8=2 times 2 times 2 12=2 times 2 times 3 4=2 times 2 3=3 lcm=2 times 2 times 2 times 3=24
5/8 times 3/3=15/24 5/12 times 2/2=10/24 3/1 times 24/24=72/24 1/4 times 6/6=6/24 2/3 times 8/8=16/24 we now have 15/24-10/24(72/24-6/24)+16/24 pemdas simplify parenthasees first 72/24-6/24=66/24
now we have 15/24-10/24(66/24)+16/24 multiply 15/24-660/576+16/24 make same bottom number 15/24 times 24/24=360/576 16/24 times 24/24=384/576 360/576-660/576+384/576 84/576 7/48
