Describe the process you would use to find the solution to the problem 3 1/4 minus1 1/3. Express your answer numerically and with a graphical representation.

1 11/12

Step-by-step explanation:

Notice (right away) that the denominators of the fractions are different (4 and 3).  

Identify the LCD:  It is 12.

Convert the two given numbers to mixed numbers with LCD 12:

3 3/12

-1  4/12

4/12 is greater in magnitude than 3/12, so we must 'borrow' from the digits' place.  Recall that 1 = 12/12.

Then 3 3/12    =    2 15/12.  -1 4/12 stays the same; it has LCD 12.

Then, perform the indicated subtraction:

2 15/12

-1   4/12

 1  11/12 (  this is the difference "3 1/4 less 1 1/3")

answer: there are 453.592 grams in a pound.

step-by-step explanation:

we can use this expression to calculate the energy gain as a particle moves with a field or the energy loss as it moves against it. (note that it is also used to define the electron-volt, a unit of energy equal to that gained by an electron as it falls through a pd of 1 v, i.e. w = 1 ev = 1.6 10-19 c 1 v = 1.6 10-19j).in fact this expression is really nothing more than the statement that potential is the potential energy per unit charge. in this case, v= w/qis simply stating that the change in potential energy(or work done) per unit charge is equal to the change in potential (or potential difference), v.student questions: uniform electric fields2electron beamcathode+5 kvanode0 v
