Answer

$g=-6.75$

Work Step by Step

In order to solve this algebraic expression, we must isolate the variable. A variable is the letter in the problem (for instance, in the equation 2x=10, x is the variable). In the expression ⅔ g=-4 ½ , g is being multiplied by a fraction, which we must cancel out. In order to cancel out a fraction being multiplied by a variable, we multiply both sides of the equation by the reciprocal of the fraction, which is the fraction flipped upside down. (For instance, the reciprocal of ⅖ is 5/2). Thus, we multiply both sides of the equation by 3/2 to obtain that $g=-6.75.$ (4 ½ equals 9/2, and 9/2 times -5/2 equals -45/4, which equals -6.75).
