$18.25 is the hourly rate because half of $12.50 is $6.25 and if you add that you will get the hourly range which is $18.25.So 18.25 is 1 and 1/2 of $12.50.
The answer is 4/15, because we have to get the denominaters to be the same, so the LCM of 5 and 15 is 15, so 15/5 is 3 and 4*3 is 12. Now, its 12/15-8/15 which is 4/15. Hope this helps!
Radical form for 112 would be 4{7 and then I think you can just search up how to reduce the 4 to 7 i don’t have the symbol btw
Deductive thinking: When you start with a given set of rules and conditions and determine what must be true as a consequence.
So the answer is true.
