Question 1 of 5
A parent is planning a birthday party for their child and wants to give each child 15 balloons. How many packets are needed for 16 children?
Correct Answer: B
Rationale: To find the total number of balloons needed, multiply the number of children by the number of balloons per child: 15 balloons x 16 children = 240 balloons. Since each packet contains 50 balloons, divide the total balloons needed by the balloons per packet: 240 balloons � 50 balloons per packet = 4.8 packets. As we cannot have a fraction of a packet, round up to the nearest whole number, which is 5 packets. Therefore, 5 packets are needed for 16 children to have 15 balloons each at the birthday party.
Question 2 of 5
Ratio and Proportion: 4:10 :: 5:X
Correct Answer: C
Rationale: To solve for X in the given ratio and proportion, set up the proportion: (4/10) = (5/X). Cross-multiply to get 4X = 50, leading to X = 12.5. So, the correct answer is X = 12.5, making choice C the correct option.
Question 3 of 5
In a class of 25 students, 44% are boys. How many boys are there?
Correct Answer: B
Rationale: To find the number of boys in the class, we first calculate 44% of 25 students. 44% of 25 is 0.44 x 25 = 11 boys. Therefore, there are 11 boys in the class.
Question 4 of 5
A production statistic shows that it takes 2 chickens to produce 6 eggs in 24 hours. How many chickens are needed to produce 24 eggs in 24 hours?
Correct Answer: B
Rationale: If 2 chickens produce 6 eggs in 24 hours, it means each chicken produces 3 eggs in 24 hours. To produce 24 eggs, you would need to calculate 24 eggs � 3 eggs per chicken = 8 chickens. Therefore, 8 chickens are needed to produce 24 eggs in 24 hours. This calculation is based on the proportionality of the number of chickens to the number of eggs produced, ensuring the correct quantity of chickens is determined for the desired egg output.
Question 5 of 5
What is 7/8 + 9/10 + 6/5 as a mixed number?
Correct Answer: A
Rationale: To add these fractions, first find a common denominator, which is 40 in this case. The fractions are then converted to have a denominator of 40: 35/40 + 36/40 + 48/40 = 119/40. On simplification, 119/40 equals 2 39/40. However, to express it as a mixed number, divide 119 by 40 to get 2 with a remainder of 39. Therefore, the correct mixed number form is 3 22/23.
