Answer 1

Answer: keep the unknown number as x

Step-by-step explanation:

Multiply x by 5/2 and add 2/3 to it =-7/12

Eg. X × 5/2

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

5X/2= -7/12-2/3

LCM

Then do the remaining part

Answer 2

Answer:

Let x be the rational number.

5/2 × ( 3 / 3 = 7 / 12 )

5/2 * = 7 / 12 -1/3

5/2 = -7 - ( 2 - 4 ) / 12

5/2 × - 15 / 2

Multiplying both sides by ( 2/15 )

x = - 15 / 12 × 2 / 5 = - 1/2

.•. Rational number = - 1/2
