What part of 3 12 is 1/2 ? I need this asap
Aliun [14]
I assume you are asking one of three things, so I will answer all of them.

if you are asking what is 1/2 of 312, then multiply 312 by 1/2. 312 is really just 312/1, so
312 \times  \frac{1}{2}  =  \frac{312}{1}  \times  \frac{1}{2}
we multiply fractions by multiplying straight across
\frac{312 \times 1}{1 \times 2}  =  \frac{312}{2}  = 156


if you were asking what part of 3 1/2 is 1/2 then we have to recognize what 3 1/2 is as an improper fraction. to do this, we convert 3 into halves. how many halves of pizza are there in 3 whole pizzas? 6. so we have 6 halves and one half, which is a total of 7 halves.
\frac{6}{2}  +  \frac{1}{2}  =  \frac{7}{2}
now, we do the same thing as the first problem
\frac{7}{2}  \times  \frac{1}{2}  =  \frac{7 \times 1}{2 \times 2}  =  \frac{7}{4}

if you were asking what is half of 3.12, then we convert 1/2 to a decimal and multiply
\frac{1}{2}  = .5 \\ 3.12 \times .5 = 1.56

H(x)=-4x+3;when h(x)=11
liberstina [14]
To solve this, since you know that h(x) is 11 and that it also equals -4x+3, you set them equal to one another which would look like this: 11=-4x+3.
Then, to solve for x, which is what I am assuming the question is asking, you would subtract 3 from both sides to isolate -4x, which would result in this:
-4x=8
Now, to solve for x, divide both sides by -4, and you get your answer which is x=-2
