.83 is the answer 5/6 = .83333333 but rounding its .83
To work out 8% of 150, you have to do 150 multiplied by 8, divided by 100.
So it should look like this: (150 × 8) ÷ 100. (Which is 12%)
You have to remember to divide by 100 at the end, because a percentage (%) is out of 100, so you have to make the number out of 100, and the only way to do that is to divide by 100.
Answer:
f(a) = 1,5
Step-by-step explanation:
-3a + 6b = a + 4b
[+3a] [+3a]
6b = 3a + 4b
[-4b] [-4b]
2b = 3a
[÷2] [÷2]
b = 1,5a
