Integrative Mathematics (Intro For Grade 6)

The place value of a digit in a number determines the position of that digit in relation to the decimal point. In the number 732,250,013, the digit 5 is in the "ten thousand" place, which means it represents a value of 50,000. Therefore, the statement is true.

The standard form of twenty billion, three thousand, eight is 20 000 003 008. This is because each place value is represented by a specific number. In this case, the number twenty billion is represented by the digits 20 followed by nine zeros. The number three thousand is represented by the digits 003, and the number eight is represented by the digit 008. Therefore, when these numbers are combined, the standard form is 20 000 003 008.

The value of the digit 4 in the number 1 200 304 is not 40. The value of a digit in a number is determined by its position. In this case, the digit 4 is in the thousands place, so its value is 4,000, not 40. Therefore, the statement is false.

The given number is 456,642,123. The "ten millions place" refers to the digit in the position that represents ten million. In this case, the digit in the ten millions place is 5.

A whole number is a number that does not have any fractional or decimal part. In the given options, only 27 019 is a whole number as it is an integer without any decimal or fractional part. 270.19, 27/19, and 27x all contain fractional or decimal parts, making them not whole numbers.

The value of 7 in the number 356 770 707 333 is 70 000 000. This is because the 7 is in the hundred millionth place, which represents a value of 70 million.

The statement is false because the expanded form of 28,933 is actually 20,000 + 8,000 + 900 + 30 + 3, not 20,000 + 80,000 + 900 + 30 + 3. The digit in the ten-thousands place is 2, not 8, so the correct expanded form should reflect that.

The given statement is true. The exponential form of 28,933 can be expressed as (2 x 10^4) + (8 x 10^3) + (9 x 10^2) + (3 x 10^1) + (3 x 10^0). This is because each digit in the number is multiplied by the corresponding power of 10, starting from the leftmost digit.

The word "exponential" is used to describe a form of expressing a number where it is raised to a power or exponent. In this context, it suggests that there are other ways to express a number that involve exponents or powers.

Whole numbers are integers that are not fractions or decimals. They include positive numbers, negative numbers, and zero. In the given options, 7 201 888.16, 1/2, and 1.2 are not whole numbers because they are either decimals or fractions. Therefore, the correct answer is 7 201 888.16, 1/2, and 1.2.
