One half is just 1÷2 which is 0.5, add the 1 makes 1.5
1 + 1/2 = 1.5
1.6 has an extra 0.1, making it greater than
1.6 > 1.5

One and a half = 1.5, so 1.6 is more than 1.5.
It's very trivial question.

Convert the fraction 3/4 to decimal form to get 3/4 = 0.75

To factor out 3/4, we divide each term by 3/4 or 0.75
It might be easier to divide by 0.75 to avoid two division symbols

So (3/4)z+6 = 0.75z+6
Divide each term (0.75z and 6) by 0.75 which is what we want to factor out

0.75z/0.75 = z
6/0.75 = 8

Therefore,
0.75z+6 = 0.75*(z+8)

Note how we can distribute the 0.75 back through to each term inside (z and 8) and we'll end up with 0.75z+6 again.

The answer in fraction form is $\frac{3}{4}(z+8)$ which is 3/4 outside the parenthesis multiplied by the group (z+8)
