Question

What part of 3 12 is 1/2 ? I need this asap

Answer 1

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 * (1)/(2) = (312)/(1) * (1)/(2)`
we multiply fractions by multiplying straight across

`(312 * 1)/(1 * 2) = (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.

`(6)/(2) + (1)/(2) = (7)/(2)`
now, we do the same thing as the first problem

`(7)/(2) * (1)/(2) = (7 * 1)/(2 * 2) = (7)/(4)`

if you were asking what is half of 3.12, then we convert 1/2 to a decimal and multiply

`(1)/(2) = .5 \\ 3.12 * .5 = 1.56`
