The answer is -1. Due to PEMDAS, you have to do whatever is inside the parentheses first. When you replace “a” and “b” in the parentheses, it will give you 1+3 which is 4. After this, you have to do 4-6 in order to get -2. Then, you have to replace 2 in the denominator. By this point, it would be -2/2, which simplified to -1.

vesna_86 [32]

Given :

Stephanie took a science exam that had two parts. Part 1: She got 16 questions correct, which was 4/5 of the number of part 1 questions. Part 2: She got 16 questions correct, which was 2/3 of the number of part 2 questions.

To Find :

The total number of questions on Stephanie's exam.

Solution :

Let, number of questions in Part 1 is x :

$16=\dfrac{4}{5}x\\\\x=20$

Let, number of questions in Part 2 is y :

$16=\dfrac{2}{3}y\\\\y=24$

Therefore, total number of questions on Stephanie's exam are 20 + 40 = 60.

Hence, this is the required solution.
