Hey there!
First, multiply the numbers 10 2/5 and 3 . . .
10 2/5 = 52/5
3 = 3/1
52 x 3 = 156
5 x 1 = 5
= 156/5
Simplifying 156/5 . . .
156/5 = 31 1/5
Now, multiply the numbers 31 1/5 and 8 1/3 . . .
31 1/5 = 156/5
8 1/3 = 25/3
156 x 25 = 3,900
5 x 3 = 15
Simplifying 3,900/15 . . .
3,900/15 = 260 <----
The correct answer to your question is 260.
Hope this helps you.
Have a great day! :)
