Answer 2

To solve the expression 0.75:(-3/20) - 8.4:(-2/3), we first need to understand what the ":" symbol represents in this context. Typically, ":" denotes division. Therefore, we can rewrite the expression as follows:

0.75 ÷ (-3/20) - 8.4 ÷ (-2/3)

Now, let's simplify the expression step by step:

Step 1: Simplify the first division. 0.75 ÷ (-3/20) = 0.75 × (-20/3) = -5

Step 2: Simplify the second division. 8.4 ÷ (-2/3) = 8.4 × (-3/2) = -12.6

Step 3: Subtract the two results. -5 - (-12.6) = -5 + 12.6 = 7.6

Therefore, 0.75:(-3/20) - 8.4:(-2/3) equals 7.6.
