Answer 1

1) 94/10 + 27/20= 188/20+27/20= 215/20= 43/4
2) 43/4: 15/8= 43/4*8/15= 86/15
3) 24*3/8= 3*3= 9
4) 86/15+9= 86/15+ 135/15= 221/15= 14 11/15

Answer 2

To simplify the expression (9 + 4) / (20) : (1 + 7/8) + 24 * (3/8), let's perform the operations step by step:

Step 1: Solve the innermost parentheses and fractions. (9 + 4) / 20 : (1 + 7/8) + 24 * (3/8) = 13 / 20 : (1 + 7/8) + 24 * (3/8) = 13 / 20 : (15/8) + 24 * (3/8)

Step 2: Simplify the addition inside the second parentheses. 13 / 20 : (15/8) + 24 * (3/8) = 13 / 20 : (15/8 + 24 * 3/8) = 13 / 20 : (15/8 + 72/8) = 13 / 20 : (87/8)

Step 3: Perform division. 13 / 20 : (87/8) = 13 / 20 * 8 / 87 = (13 * 8) / (20 * 87) = 104 / 1740 = 26 / 435

So, the simplified result of the expression is 26 / 435.
