Convert the rational number to decimals, then solve it as a decimal instead, (with the optional choice of re-converting it back to rational).

Answer:

k = 3.75

Step-by-step explanation:

Note the equal sign, what you do to one side, you do to the other. Isolate the variable, k. Divide -1.2 from both sides:

(-4.5)/(-1.2) = (-1.2k)/-1.2

-4.5/-1.2 = k

k = -4.5/-1.2

k = 3.75

3.75 is your answer for k.

Muhammad ate an average of 2.5% cookies per day
AleksandrR [38]
A = 2.5x , where x = 7 since there is 7 days in a week. So it would be 2.5(7)

B = 2.5(30) where 30 represents how many days. So he eats 75 cookies in 30 days.

Correct me if I am wrong.
