(4•24):(42•8)=96:336=2/7

Answer 3

Let's solve these mathematical expressions step by step:

1. (12 * 45) / 40 First, multiply 12 by 45, which equals 540. Then, divide 540 by 40. 540 / 40 = 13.5

So, (12 * 45) / 40 = 13.5

2. (4 * 24) / (42 * 8) First, multiply 4 by 24, which equals 96. Then, multiply 42 by 8, which equals 336. Finally, divide 96 by 336. 96 / 336 ≈ 0.2857 (rounded to four decimal places)

So, (4 * 24) / (42 * 8) ≈ 0.2857
