Question

What is the 20th digit after the decimal point of the sum of the decimal equivalents for the fractions $\frac{1}{7}$ and $\frac{1}{3}$?

Answer 1

Answer:

7

Step-by-step explanation:

1/7+1/3= 3/21+7/21= 10/21= 0.476190

the 6 digits after the decimal point get repeated

6*3= 18- three full cycles and the second digit after 3 cycles = 7 so the 20th digit is 7
