Just read carefully - 3/5 of 5/8 of 2/3 in correct order simply means if you have 5/8 of 2/3 then what is 3/5 of that?

5/8 x 2/3 = 10/24= 5/12 x 3/5 = 15/60 = 1/4

Thus
"A"

$$\frac{3}{5}*\frac{5}{8}*\frac{2}{3}$$ = $$\frac{1}{4}$$

Seems simple, but I can see the possibility of arithmetic mistakes, so I suspect this question tests the rules that "of" = multiply, that order in this case does not matter (you don't have to calculate 5/8 of 2/3 first, e.g.), and that one should "cancel" before solving.

(3/5) * (5/8) * (2/3):

The two 3s, factored out (canceled), leave 1 in numerator and 1 in denominator

The two 5s, factored out, also leave 1 in both numerator and denominator

The 2, factored out of 2 and 8, leaves 1 in the numerator and 4 in the denominator:

(1/1) * (1/4) * (1/1) =

$$\frac{1 * 1 * 1}{1 * 4 * 1}$$

Answer A: $$\frac{1}{4}$$

Let’s first determine 3/5 of 5/8:

(3/5) x (5/8) = 3/8

Now let’s determine 3/8 of 2/3:

(3/8) x (2/3) = 1/4

$$\frac{3}{5} * \frac{5}{8} * \frac{2}{3} = \frac{2}{8} = \frac{1}{4}$$. Ans - A.
