Answer 2

Let's solve the given expression step by step:

3:3(3/4) + 2(2/5) * 2(1/2) - 3(5/6)

First, let's simplify the fractions:

3/4 = 0.75 2/5 = 0.4 1/2 = 0.5 5/6 = 0.8333...

Now we can substitute these values into the expression:

3:3 * 0.75 + 2 * 0.4 * 2 * 0.5 - 3 * 0.8333...

Next, let's perform the multiplications:

3:3 * 0.75 = 1 * 0.75 = 0.75 2 * 0.4 * 2 * 0.5 = 0.8 3 * 0.8333... = 2.5 (approximately, since 0.8333... is close to 5/6)

Now the expression becomes:

0.75 + 0.8 - 2.5

Finally, let's add and subtract:

0.75 + 0.8 - 2.5 = -0.95

So, the value of the expression is approximately -0.95.
