One one fourth times negative three four fifths

-4.75 or -4 3/4

Step-by-step explanation:

1 1/4 * -3 4/5 = -4.75 or -4 3/4

-19/4 or -4 3/4

Step-by-step explanation:

1 1/4 * - 3 4/5

You would first turn both fractions into "improper" fractions

1 1/4 -> 5/4

-3 4/5 -> -19/5

5/4 * - 19/5

A negative number multiplied by a positive number is a negative number.

You could either cross cancel the 5's to get: -19/4 or -4 3/4

Or you could do this:

In multiplication, you multiply straight across ->

5 * -19                                  -95

 Which is equal to:  

4 * 5                                     20

-95/20 reduced is -19/4, or -4 3/4

both equations and proportions are better.
