What is 4.62 expressed as the quotient of two integers in simplest form?
erik [133]
Multiply 4.62 by a number that to get an integer.
Such as multiply by 5 is 23.10 so to get rid of 0.1, just multiply by 50 then it becomes 231.

so that means...
4.62 = 231 / 50

or a simple answer would be multiply by 100, then you get 462.

so....
4.62 = 462 / 100
And then simplify, it is divisible by 2 so the answer is 231/50

Answer:

14s^4-7s^2+15

Step-by-step explanation:

At the beginning the only bracket that is changing is the 3rd one because of the minus. (12s^4-6s^2+4s)+(6s^4-4s+27)-4s^4+s^2+12 then open the rest of the brackets. And start calculating.i will just to show you which ones u calculate together. (I'll separate the numbers depending on what they're squared to).

12s^4+6s^4-4s^4=14s^4

-6s^2-s^2=7s^2

27-12=15

All together is 14s^4-7s^2+15
