To simplify the fraction 12/22, we can divide both the numerator and denominator by their greatest common divisor, which is 2. 12 divided by 2 is 6, and 22 divided by 2 is 11. Therefore, the simplest form of 12/22 is 6/11.

The correct answer is 87 R2. This means that when 263 is divided by 3, the quotient is 87 and the remainder is 2.

The most reasonable estimate for 6 x 379 is 2,400. This can be determined by rounding 379 to the nearest hundred, which is 400, and then multiplying it by 6. Since 400 is close to 379, the product of 6 x 400 is a reasonable estimate for 6 x 379. The product of 6 x 400 is 2,400.

A segment in a circle is a part of the circle that is enclosed by a chord. A chord is a line segment that connects two points on the circumference of the circle. In this case, the segment mentioned in the question is not a chord because it does not connect two points on the circumference. Instead, it is a radius, which is a line segment that connects the center of the circle to any point on the circumference. Therefore, the correct answer is radius.

The fraction 7/10 can be written as a decimal by dividing 7 by 10. When 7 is divided by 10, the quotient is 0.7. Therefore, the correct answer is 0.7.

The number expression "10+5" represents "5 more than 10" because when you add 5 to 10, you get a sum of 15, which is 5 more than the original number 10.

To convert feet to yards, divide the number of feet by 3, since there are 3 feet in a yard. In this case, 36 feet divided by 3 equals 12 yards.

The range is the difference between the highest and lowest values in a data set. In this case, the highest shoe size is 12 and the lowest shoe size is 4. Therefore, the range is 12 - 4 = 8.

The total cost of the fabric can be calculated by multiplying the number of yards (5) by the cost per yard ($2.79). Therefore, the total cost of the fabric is $13.95.

There are 10 millimeters in 1 centimeter, so to find out how many millimeters are in 2 centimeters, we multiply 2 by 10, which equals 20.

The most reasonable estimate for 12 x 472 is 5,000 because it is the closest option to the actual product. Multiplying 12 by 472 gives us 5,664, which is closest to 5,000 compared to the other options.

The elapsed time from 7:30 A.M. to 9:12 A.M. is 1 hour and 42 minutes. To find the elapsed time, subtract the starting time from the ending time. In this case, subtracting 7:30 A.M. from 9:12 A.M. gives us 1 hour and 42 minutes.

The given number, 577,312, is rounded to the nearest thousand. To round a number to the nearest thousand, we look at the hundreds place. If the digit in the hundreds place is 5 or greater, we round up to the next thousand. In this case, the digit in the hundreds place is 3, which is less than 5. Therefore, we round down to the nearest thousand, which is 577,000.

To convert a mixed number to an improper fraction, multiply the whole number by the denominator of the fraction and add the numerator. In this case, multiplying 3 by 8 gives us 24, and adding the numerator 8 gives us 32. Therefore, 3 1/8 can be written as the improper fraction 32/8, which can be simplified to 25/8.

132 is divisible by 3 because the sum of its digits (1 + 3 + 2 = 6) is divisible by 3.

To divide 5,400 by 90 mentally, we can start by dividing each number by 10. 5,400 divided by 10 is 540, and 90 divided by 10 is 9. Then, we can divide 540 by 9, which gives us 60. Therefore, the answer is 60.

The perimeter of a rectangle is calculated by adding up all the sides of the rectangle. In this case, the two sides given are 14 m and 20 m. To find the perimeter, we add these two sides together: 14 m + 20 m = 34 m. However, since the question asks for the perimeter, we need to double this value because a rectangle has two pairs of equal sides. Therefore, the perimeter of the rectangle is 2 * 34 m = 68 m. Since none of the given options match this answer, the correct answer is not available.

The probability of spinning a 5 when spinning the spinner once is impossible because the options provided do not include a 5.

The area of a rectangle is calculated by multiplying its length by its width. Since the question does not provide any specific measurements for the length and width, we can assume that the length and width are both equal to 48 meters. Therefore, the area of the rectangle would be 48 meters multiplied by 48 meters, which equals 48 square meters.

To round a number to the nearest tenth, we look at the digit in the hundredth place. In this case, the digit in the hundredth place is 8. Since 8 is greater than or equal to 5, we round up the digit in the tenths place, which is 1, to the next higher number. Therefore, 21.83 rounds to 21.8.
