Easy math, % = number you multiply by when you MOVE the decimal TWICE to the LEFT. For example 56% would be .56 and 9% would be .09, and then you just multiply it with the 40 mins (.20) and all the other ones :)

Okay so start with multiplying 93 * 7

So 3 x 7= 21

9 X 7 +63, carry the 2 = 651

Then 8 x 93
Remember that first is a zero.
8 X 3= 24
8 X 9= 72, carry the 2= 74
So that is 7440
Now
0651
+7440
8091
And that's the answer
