True. No imaginary number is considered "whole", all whole numbers are rational and real.
Divide 5.60 by 70 and that's the price per ounce
Add 8 to 46. Then divide 54/8 to get 6.75 and t=6.75
16.445 I have no expectation sorry.
4 divided by 2/3 equals 6. And 2/3 divided by 4 equals about 0.1666
First you would write it as 4/1 divided by 2/3, then you would you keep, change, flip. If you do not know how to keep,change,flip just keep the first fraction then change the division sign to multiplication then flip the last fraction. Then you should get the answer. And if you need to simplify make sure to do that.
