Answer 16

Certainly! Here's an alternative way to write the expanded form of 23.75:

(2 * 10) + (3 * 1) + (7 * 0.1) + (5 * 0.01)

Answer 17

Certainly! Here's the expanded factors form of 23.75:

(2 * 10) + (3 * 1) + (7 * (1/10)) + (5 * (1/100))

Answer 18

Certainly! Here's the expanded form of 357.25:

(3 * 100) + (5 * 10) + (7 * 1) + (2 * (1/10)) + (5 * (1/100))

And here it is in expanded factors form:

(3 * 10^2) + (5 * 10^1) + (7 * 10^0) + (2 * 10^(-1)) + (5 * 10^(-2))

Answer 19

Sure! Here's the expanded form of 8,471.716:

(8 * 1000) + (4 * 100) + (7 * 10) + (1 * 1) + (7 * (1/10)) + (1 * (1/100)) + (6 * (1/1000))

And here it is in expanded factors form:

(8 * 10^3) + (4 * 10^2) + (7 * 10^1) + (1 * 10^0) + (7 * 10^(-1)) + (1 * 10^(-2)) + (6 * 10^(-3))

Answer 21

To determine the number of digits in the repeating cycle of a number when expressed as a fraction, we need to find its prime factors.

Let's start by considering 1727. We notice that it is not divisible by 2, so we move on to 3. Dividing 1727 by 3, we get 575 remainder 2.

Next, we try dividing by 7, but it doesn't divide evenly. Another prime number to consider is 11. After dividing 1727 by 11, we get 157 remainder 0.

So, we have prime factors of 3, 11, and 157.

Now, let's analyze the prime factors to determine the length of the repeating cycle. Both 3 and 11 are factors of 10 (3 * 11 = 33), which implies that the decimal expansion will repeat every 10 digits. However, 157 is prime and does not divide evenly into 10.

Therefore, the repeating cycle of 1727 when expressed as a decimal would be 10 digits.

Answer 22

No problem! The repeating cycle of a fraction can be determined by its denominator. To find the repeating cycle of 17/27, we need to prime factorize the denominator, which is 27.

27 can be factorized as 3 * 3 * 3 or 3^3.

The length of the repeating cycle in a fraction with a denominator of 3^n is n. In the case of 27, n is equal to 3.

Therefore, the repeating cycle of 17/27 is 3 digits long.

Answer 23

To determine which of the given rational numbers can be expressed as a repeating decimal, we need to check their denominators for any factors other than 2 and 5, since those factors result in a terminating decimal.

Let's check the denominators for each given rational number:

- 7/8: The denominator, 8, only contains 2 as a factor, so it can be expressed as a terminating decimal.
- 5/12: The denominator, 12, contains 2 and 3 as factors, so it can be expressed as a repeating decimal.
- 17/25: The denominator, 25, only contains 5 as a factor, so it can be expressed as a terminating decimal.
- 31/40: The denominator, 40, contains 2 and 5 as factors, so it can be expressed as a terminating decimal.

Based on this analysis, the only rational number that can be expressed as a repeating decimal is 5/12.

Answer 24

To express 7/13 as a repeating decimal, we need to perform long division:

0.
13 | 7.000
- 6.50
------
50
-39
----
110
-104
----
60
- 52
----
80
- 78
----
20

The remainder 20 repeats.

Therefore, 7/13 as a repeating decimal is 0.538461538461... with the digits 538461 repeating.

Answer 25

To convert the repeating decimal 0.8¯¯¯ to a rational number, we can represent it as a fraction.

Let's use the variable x to represent the repeating decimal:

x = 0.8¯¯¯

To eliminate the repeating part, we multiply x by a power of 10 that moves the decimal point just before the repeating part:

10x = 8.¯¯¯

Next, we subtract x from 10x to eliminate the repeating part:

10x - x = 8.¯¯¯ - 0.¯¯¯

This simplifies to:

9x = 8

Now, we solve for x by dividing both sides of the equation by 9:

x = 8/9

Therefore, 0.8¯¯¯ can be expressed as the rational number 8/9.

Answer 26

To convert the repeating decimal 0.82¯¯¯¯¯ to a rational number, we begin by setting x equal to 0.82¯¯¯¯¯.

x = 0.82¯¯¯¯¯

To eliminate the repeating part, we need to multiply x by a power of 10 that moves the decimal point just before the repeating part. Since there are two repeating digits (82), we need to multiply by 100 (10^2):

100x = 82.82¯¯¯¯¯

Therefore, to eliminate the repeating part of the decimal, we multiply both sides of the equation by 100.
