Write -39/12 as a mixed number in reduced form.

Step-by-step explanation:

We have:

the first thing we can do is reduce this expression by dividing each number by 3:

Now that we have reduced the expression, we can still represent this number as a mixed number.

if we divide -13 by 4 we don't get an exact number (we get -3.25) thus we are going to have a mixed number which is formed by an integer and a fraction.

The integer in the mixed number we find by how many time does the number 4 fit into the number 13 exactly - the answer to this is 3 times. And since the number is negative the integer of the mixed number is -3.

The fraction is how much is letf after we take the whole number out, this is, 4 fits 3 times into the number 13 because 4*3=12 but have left, this will be the fraction part of the mixed number

so the answer is

rectangle: 9 1/8 x 4 1/9 = 37 37/72in

parallelogram: b times h= 10.3 x 6.2 = 63.86

trapezoid: a+b/2 times h= 42.5

volume of prism: l times w times h= 36
