Math Test Quiz For 5th Grade

The question is asking for the longest measurement among decimeter, centimeter, meter, and millimeter. The correct answer is 1 meter, as it is the largest unit of length compared to the other options. A decimeter is 1/10th of a meter, a centimeter is 1/100th of a meter, and a millimeter is 1/1000th of a meter. Therefore, 1 meter is the longest measurement among the given options.

A kilometer is longer than a hectometer, dekameter, and meter. The prefix "kilo-" denotes a factor of 1000, so a kilometer is equal to 1000 meters. In comparison, a hectometer is equal to 100 meters, a dekameter is equal to 10 meters, and a meter is the base unit of length in the metric system. Therefore, a kilometer is the longest unit of measurement among the options given.

The shortest length is 1 millimeter. Millimeters are smaller than centimeters, decimeters, and meters.

To write 18/50 as a percent, you need to divide the numerator (18) by the denominator (50) and then multiply the result by 100. This can be done as follows: 18/50 = 0.36. Multiplying 0.36 by 100 gives us 36%. Therefore, the correct answer is 36%.

There are 4 quarts in a gallon. This is a standard conversion in the US customary system of measurement. A gallon is divided into 4 equal parts, each part being a quart. Therefore, if you have a gallon and you want to know how many quarts it contains, the answer is 4.

To convert centimeters to decimeters, we divide the value by 10. Since there are 10 centimeters in 1 decimeter, dividing 26 centimeters by 10 gives us 2.6 decimeters. Therefore, the correct answer is 2.6 decimeters.

The point (1, 7) lies on the line y = 7 because the y-coordinate of the point is equal to the constant value of 7 in the equation.

The area of a triangle is calculated by multiplying the base by the height and dividing the result by 2. In this case, the base is 12 centimeters and the height is 5 centimeters. Therefore, the area of the triangle is (12 * 5) / 2 = 60 / 2 = 30 square centimeters.

The area of a circle can be calculated using the formula A = πr^2, where A is the area and r is the radius. In this case, the diameter is given as 10 inches, so the radius would be half of that, which is 5 inches. Plugging this value into the formula, we get A = 3.14 * 5^2 = 3.14 * 25 = 78.5 square inches.

The least common denominator is the smallest number that both denominators can evenly divide into. In this case, the denominators are 3 and 21. The number 21 is the least common denominator because both 3 and 21 can evenly divide into it.

The correct answer is 7-Jun because the ratio "6 to 7" can also be written as "7-Jun" where 7 is the numerator and Jun is the denominator.

The given question asks for the result of subtracting 3 3/10 from 4 1/10. To solve this, we need to subtract the whole numbers and the fractions separately. Subtracting the whole numbers gives us 1. Next, subtracting the fractions gives us 1/10. Therefore, the result is 1 1/10.

The circumference of a circle can be found by multiplying the diameter by pi (π). In this case, the diameter is given as 100 feet and the value of pi is given as 3.14. Therefore, the circumference can be calculated as 100 * 3.14 = 314 feet.

To convert 40 ounces to pounds and ounces, we divide the total number of ounces by 16 (since there are 16 ounces in a pound). In this case, 40 divided by 16 equals 2 with a remainder of 8. Therefore, the answer is 2 pounds and 8 ounces.
