64 * 60 * 60 * 10 = ?
3 1/6 x 9/11 x 6/17
19/6 * 9/11 * 6/17 = ?
Multiply the numerators and then multiply the denominators. The numerator in the answer is 1026.
6/25 / 2/15
6/25 * 15/2 = ?

I will solve one of the questions only.
A computer can execute 64 instructions per second. How many instructions can it execute in 10 minutes?
Let x = the number of instructions in 10 minutes.
We use the following proportion:
64 instructions/x instructions = 1 second/600 seconds
In short, we can write it this way:
64/x = 1/600
Where did 600 come from?
I multiplied 10 minutes by 60 seconds per minute.
64/x = 1/600
Crossmultiply and solve for x.
x = 64 x 600
x = 38,400
Done!
