The answer is D.

If you multiply them all together the answer (without simplifying), it should equal 210/9, you then simplify the numerator and denominator by 3 and you get 70/3.

Answer:

D

Step-by-step explanation:

Given

\frac{5}{3} × \frac{2}{3} × \frac{21}{1}

Multiply numerators/ denominators

= \frac{5(2)(21)}{3(3)(1)}

= \frac{210}{9}

Cancel the numerator/denominator by dividing both by 3

= \frac{70}{3} → D
