Question

rational number such that when we mutiply it by 5/2 add 2/3 to the product we get -7/12 and what is the number ?

Answer 1

Let the number be y

y x 5/2 + 2/3 = -7/12

---------------------------------------------------------------------------------------------------

Multiply y and 5/2:

5y/2 + 2/3 = -7/12

---------------------------------------------------------------------------------------------------

Subtract 2/3 from both sides:

5y/2 = -5/4

---------------------------------------------------------------------------------------------------

Cross multiply:

4(5y) = -5(2)

---------------------------------------------------------------------------------------------------

Remove brackets:

20y = -10

---------------------------------------------------------------------------------------------------

Divide both sides by 20:

y = -1/2

---------------------------------------------------------------------------------------------------

Answer: The number is -1/2

Answer 2

Let the number be x
( x X 5/2) +2/3 = -7/12
