Part 1 of 2 The IQ (intelligence quotient) is found by dividing the mental age (MA), as indicated on standard tests, by the chronological age (CA) and multiplying by 100. For example, if a child has a mental age of 12 and a chronological age of 8, the calculated IQ is 150. If a 7-year-old girl has an IQ of 160, compute her mental age. Write the equation required to find the solution, using x to represent the chronological age of the girl. (Use integers or fractions for any numbers in the equation. Do not simplify) www
