Answer:
X = -3333/100000
Step-by-step explanation:
Given that a rational number is such that when you multiply it by 5/2 and add 2/3 to the product you get 7/12, to determine what is the number the following calculation must be performed:
X x 5/2 + 2/3 = 7/12
2.5X + 0.666 = 0.583333
2.5X = 0.58333 - 0.6666
X = -0.08333 / 2.5
X = -0.033333
X = -3333/100000.
