Step-by-Step Solution

To solve this problem, we'll follow these steps according to the order of operations:

  • Step 1: Simplify the expression 35:(75)(2+9:32) 35:(7 \cdot 5)-(2+9:\frac{3}{2}) .
  • Step 2: Calculate 75 7 \cdot 5 and 9:32 9:\frac{3}{2} .
  • Step 3: Simplify the division 35:35 35:35 as well as 9:32 9:\frac{3}{2} .
  • Step 4: Evaluate the expression step-by-step.

Now, let's solve the expression:

Step 1: Calculate the multiplication: 75=35 7 \cdot 5 = 35 .

Step 2: Calculate the division: 9:32=9×23=6 9:\frac{3}{2} = 9 \times \frac{2}{3} = 6 . We use the reciprocal of 32\frac{3}{2}.

Step 3: Substitute back into the original expression: 35:35(2+6)=35:358 35:35 - (2 + 6) = 35:35 - 8 .

Step 4: Simplify the division: 35:35=1 35:35 = 1 .

Step 5: Calculate the subtraction: 18=7 1 - 8 = -7 .

Therefore, the solution to the problem is 7 -7 .
