What is the value of the expression
(need to go from mixed to improper fractions and from decimal fractions)
6 3/4(-11.5)
6 3/4 = (24+3)/ 4 = 27/4
27/4 * (-11.5)
11. 5 = 11 1/2 = (22+1)/ 2 = 23/2
so then,
27/4 * (-11.5)
= 27/4 * (-23/2) (the result is negative value )
= - (27*23)/ (4*2)
= - (621)/ 8
= - (616 + 5)/ 8
= - 77 5 /8
