1. Convert 140% into a decimal (1.4). >> 2. Your score (y) is 1.4 times that of your friend's score (x). Written as an equation, this would be 1.4x = y >> 3. Input your known factor (y), and you have 1.4x = 86.8 >> 4. Divide both sides by 1.4, isolating your unknown (x = 86.8/1.4) >> Anthony - Unlocking potential through love of learning
