77 5/8

Step-by-step explanation:

a) Multiply the whole number 6 by the denominator 4. Whole number 6 equally 6 * 4/4

= 24/4

b) Add the answer from the previous step 24 to the numerator 3. New numerator is 24 + 3 = 27

c) Write a previous answer (new numerator 27) over the denominator 4.

Conversion a decimal number to a fraction: -11.5 = -115/10

= -23/2

a) Write down the decimal -11.5 divided by 1: -11.5 = -11.5/1

b) Multiply both top and bottom by 10 for every number after the decimal point. (For example, if there are two numbers after the decimal point, then use 100, if there are three then use 1000, etc.)

-11.5/1

= -115/10

c) Simplify and reduce the fraction

-115/10

= -23 * 5/2*5

= -23 * 5/2*5

= -23/2

Multiple: 27/4

* (-11.5) = 27 · (-23)/4 times5

= -621/8
