Math Grade 8 Word Problem Set 1 Worksheet Answer Key
Answer Key:
1. The answer to the first problem is 24. To find the total number of apples, add the number of red and green apples together: 8 + 16 = 24.
2. The answer to the second problem is 75. To find the percentage of girls, divide the number of girls by the total number of students and multiply by 100: (30 / 40) x 100 = 75%.
3. The answer to the third problem is 10. To find the missing number in the pattern, subtract 3 from the previous number each time: 15 – 3 = 12, 12 – 3 = 9, 9 – 3 = 6, 6 – 3 = 3, 3 – 3 = 0, 0 – 3 = -3, -3 – 3 = -6, -6 – 3 = -9, -9 – 3 = -12, -12 – 3 = -15.
4. The answer to the fourth problem is 60. To find the area of the rectangle, multiply the length by the width: 12 x 5 = 60 square units.
5. The answer to the fifth problem is 42. To find the total cost, multiply the price per pound by the number of pounds: $14 x 3 = $42.
By using this answer key, students can review their work and understand the steps involved in solving each word problem. Practicing with word problems is essential for mastering math concepts and developing problem-solving skills. With continued practice, students can become more confident in tackling challenging math problems and excel in their mathematical studies.
