Division is one of the four fundamental arithmetic operations. Andrew is faster than Noah.
The division is one of the four fundamental arithmetic operations, which tells us how the numbers are combined to form a new one.
Given that Andre can now complete 135 multiplication facts in 90 seconds.
A.) If Andre is answering questions at a constant rate, then the number of facts that Andre can answer per second can be written as,
Number of facts per seconds = 135 facts / 90 seconds
= 1.5 facts per seconds
B.) Noah also works at a constant rate, and he can complete 75 facts in 1 minute. Therefore, the number of facts that Noah can answer per second can be written as,
Number of facts per seconds = 75 facts / 60 seconds
= 1.25 facts per seconds
Now, since the number of facts that Andrew can read in a second is 1.5 facts, while the number of facts that Noah can read in a second is 1.25 facts.
Hence, Andrew is faster than Noah.
