Answer:
33 1/3
Step-by-step explanation:
turn to improper for a simpler answer
6 2/3 = 20/3
20/3 ÷ 1/5
whenever you divide fractions, you change the symbol to multiplication and divide with the reciprocal, so you get:

3 *1 = 3
100/3
is equal to 33 1/3

Answer 420.
a, is the first term. d is difference.
Since this is an arithmetic progression, I use this formula.
Un = nth term
Sn = sum of terms.
First find the number of terms, which is 20.
Then use the second formula to find the sum.
B. A and C, they both have area of 48.
