6000:(20×5)×6

To calculate this expression using the order of operations (PEMDAS/BODMAS), we start with the parentheses/brackets first:

(20 × 5) = 100

Now, we can substitute that value back into the expression:

6000 : (100 × 6)

Next, we perform the multiplication:

100 × 6 = 600

Substituting that result back into the expression:

6000 : 600

Finally, we perform the division:

6000 ÷ 600 = 10

So, 6000:(20×5)×6 equals 10.
