If you mean as a fraction:0.54 repeating as a fraction is 54/99.
5/3 is already in its simplest form. It can't be equally divided. It can only be turned into a proper fraction. (1 2/3)
Answer:
See below in bold.
Step-by-step explanation:
The formula is Tn = n(n + 1) / 2
The first triangular number is 1(1+1) / 2 = 2/2 = 1.
So the 15th = 15(15+1) / 2 = 120.
and the 19th = (19 * 20) / 2 = 190.
If h(t)=-20+11t and you wish to evaluate h(11):
h(11)=-20+11(11)
h(11)=-20+121
h(11)=101
