Question

Evaluate the equation. n- 1 1/3 = 5/7

Answer 1

Answer:

The choice A .

$n = 2 \frac{1}{21}$

Step-by-step explanation:

$n - 1 \frac{1}{3} = \frac{5}{7} \\ \\ n - \frac{4}{3} = \frac{5}{7} \\ \\ n = \frac{5}{7} + \frac{4}{3} \\ \\ n = \frac{15}{21} + \frac{28}{21} \\ \\ n = \frac{43}{21} = 2 \frac{1}{21}$

Answer 2

N = 2 1/21, so A.

n - 28/21 = 15/21

n = 43/21
