5 is bigger than 0.25. Which is the biggest of these decimal numbers?

Here are the solutions to the problems: 5. 0.5 is bigger than 0.25. Which is the biggest of these decimal numbers? A) 0.12 B) 0.3 C) 0.125 D) 0.09 E) 0.087 Step 1: Compare the digits in the tenths place for all options. • 0.12 → 1 • 0.3 → 3 • 0.125 → 1 • 0.09 → 0 • 0.087 → 0 Step 2: Identify the largest digit in the tenths place. The largest digit in the tenths place is 3, which corresponds to 0.3. B) 0.3 6. Class one has a total number of 123 pupils. If there are 19 more boys than girls. How many girls are there in the class? A) 71 B) 19 C) 52 D) 80 E) 68 Step 1: Define variables for the number of boys and girls. Let B be the number of boys and G be the number of girls. Step 2: Set up equations based on the given information. Total pupils: B + G = 123 Boys are 19 more than girls: B = G + 19 Step 3: Substitute the second equation into the first equation and solve for G. (G + 19) + G = 123 2G + 19 = 123 2G = 123 - 19 2G = 104 G = (104)/(2) G = 52 C) 52 7. A father gave half of his money to his son. And one sixth to his daughter how much is the father left with if he had 180000frs? A) 5000frs B) 60000frs C) 85000frs D) 120000frs E) 87500frs Step 1: Calculate the amount given to the son. Money to son = (1)/(2) × 180000 FRS = 90000 FRS. Step 2: Calculate the amount given to the daughter. Money to daughter = (1)/(6) × 180000 FRS = 30000 FRS. Step 3: Calculate the total amount given away. Total given away = 90000 FRS + 30000 FRS = 120000 FRS. Step 4: Calculate the amount remaining with the father. Money left = 180000 FRS - 120000 FRS = 60000 FRS. B) 60000frs 8. (1)/(2) of 40 = 20, what is (3)/(6) of 30? A) 45 B) 54 C) 15 D) 40 E) 60 Step 1: Simplify the fraction (3)/(6). (3)/(6) = (1)/(2). Step 2: Calculate (1)/(2) of 30. (1)/(2) × 30 = 15. C) 15 9. 38.9454 brought to 3 decimal places is 38.945. What is 25.59467 brought to 3 decimal places? A) 25.50 B) 25.546 C) 25.495 D) 25.49 E) 25.595 Step 1: Identify the digit in the fourth decimal place of 25.59467. The number is 25.59467. The fourth decimal place is 6. Step 2: Apply the rounding rule. Since the fourth decimal place (6) is 5 or greater, round up the third decimal place. The third decimal place is 4, so it rounds up to 5. Step 3: Write the number rounded to 3 decimal places. 25.59467 rounded to 3 decimal places is 25.595. E) 25.595 10. If I add 4 to a number and square it, the answer is 121; what is the number? A) 12 B) 20 C) 7 D) 8 E) 14 Step 1: Let the unknown number be x. Translate the problem into an algebraic equation: (x + 4)^2 = 121. Step 2: Take the square root of both sides of the equation. sqrt((x + 4)^2) = sqrt(121) x + 4 = ± 11 Step 3: Solve for x for both positive and negative values. Case 1: x + 4 = 11 x = 11 - 4 x = 7 Case 2: x + 4 = -11 x = -11 - 4 x = -15 Step 4: Choose the answer from the given options. Since 7 is an option and -15 is not, the number is 7.
