### Introduction

Hi, students! If you’re reading this, it means you’ve just taken Lesson 4 Exit Ticket 4.2 and are curious about the correct answers. Don’t worry, we’ve got you covered! In this blog post, we’ll be discussing the answer key to help you understand the concept deeper and ace the exam.

### Blog Body

#### Let’s begin with the first question.

It asks, “What is the value of 84 ÷ 4 × 3?”. The answer is 63. The proper order of operations must be followed, which is multiplication first, followed by division. This means that 84 ÷ (4 × 3) equals 84 ÷ 12, which equals 7. The correct answer, therefore, is 7 × 3 = 21.

#### The second question is quite tricky.

It asks, “What fraction of the shaded region in the figure below represents the number of 0.25 cents in 8.00 dollars?”. The answer is 1/8. To figure this out, you need to count the number of squares that are shaded and divide that by the total number of squares. In this case, there are 32 squares shaded, which is equal to $8.00 ÷ $0.25. The total number of squares is 256. Thus, your final answer should be 32/256, or 1/8.

#### The third question is fairly straightforward.

It says, “What is the product of 7 and 0.16?”. The answer is 1.12. To arrive at this answer, you need to multiply 7 by 0.16. Simply move the decimal point one place to the right, and you’ll get your answer.

#### The fourth question asks,

“Express 0.027 as a percent”. The answer is 2.7%. To convert a decimal to a percentage, you need to move the decimal point two places to the right. Thus, 0.027 = 2.7%.

#### The last question asks,

“What value of n makes the equation true: 0.6n – 1.4 = 4.2?”. The answer is 11. To solve for n, you’ll need to isolate n on one side of the equation by adding 1.4 to both sides. You’ll get 0.6n = 5.6. Solve for n by dividing both sides by 0.6 and you’ll get n = 11.
