In subtracting fractions with regrouping. what is 7 - 3 1/2?

7/2

Step-by-step explanation:

Step 1:  Convert the mixed fraction to an improper fraction

   3 1/2   is     7/2              (multiply the denominator by the whole number,

                                            then add the numerator, leave that new number

                                             over the original denominator)

Now our expression is 7 - 7/2

Step 2:  Find a common denominator

The common denominator is 2, so multiply 7 by 2/2

7(2/2) - 7/2

     14/2 - 7/2                    (14/2 = 7, but now we can combine fractions)

Step 3:   Add or subtract numerators, here it's subtraction

    14/2 - 7/2 = (14 - 7)/2    = 7/2

the length of o'p' is .

step-by-step explanation:

it is given that the quadrilateral m'n'o'p' is the image of quadrilateral mnop after dilation.

the center of dilation is origin and the scale factor is 1.5.

in dilation the image and preimge are similar figures. it means the sides of image and preimage are proportional.

the scale factor is defined as

the scale factor is 1.5.

multiply both sides by op.

note: if the value of op is given, then multiply the value of op with 1.5 to get the length of side o'p'.

therefore length of o'p' is .
