The answer is: " 9/5 " . __________________________________________________ Explanation: __________________________________________________ 4.50 / 2.50 = 4.5/2.5 ; {Note: the "zeros" cancel out.}.
Now, we can multiply Both the numerator AND the denominator by "10" (note that we multiple both the numerator AND the denominator by the same number to retain the same value); to "eliminate the decimal points" ;
4.5/2.5 = (4.5 * 10) / (2.5 *10) = 45/25 .
Now, we can further simplify this ratio; as we would a fraction, by dividing both the numerator AND the denominator by "5" ; as follows:
(45÷5) / (25÷5) = 9/5 ; which is our answer; since the question asks to "write as a fraction, in simplest form, with a whole number in BOTH the number and the denominator. ____________________________________________________ The answer is: " 9/5 " . ____________________________________________________
I think as in whole numbers in numerator it should be in improper fraction since 4.5= 4wholes and 5/10 it's 9/2?
and 2.5 in mixed fraction is 2 wholes 5/10 in improper is 5/2 unless you say mixed fraction is okay to leave if for the answer than it's respectively 4wholes 1/2 and 2wholes 1/2?
I'm not sure but I learnt this in my school and it goes like this
Multiply both sides of the equation by 12. Move the variables to the left-hand side and change its sign. Move the constant to the left-hand side and change its sign. Collect like terms. Add the numbers. Divide both sides of the equation by 12.
1/2 x - 5= - 1/2 x + 19/4 6x -20= - 6x + 57 6x + 6x= 57 + 20 12x= 57 + 20 12x= 77 ANSWER x = 77/12 Alternative Form . x = 6 5/12, x= 6.416
