15/40 is a terminating decimal

ollegr [7]3 years ago
4 0

Answer:

See below  

Step-by-step explanation:

If the denominator of a fraction has <em>only factors of 2 and 5</em>, the decimal expression <em>terminates</em>.  

If the denominator contains a factor <em>other than 2 or 5,</em> then the decimal expression <em>repeats. </em>

56/72 is a repeating decimal

72 contains a factor of 9.

12/30 is a terminating decimal.

30 contains factors of 2 and 5

15/40 is a terminating decimal.

40 contains factors of 2 and 5

12/37 is a repeating decimal.

37 does not contain factors of 2 or 5.

Which of the following answer choices would satisfy the inequality below? -2.74 &lt; x &lt; -2.35​
Helga [31]

Answer: -3pi/4

Step-by-step explanation:

-3pi/4 = -2.35619

-2.35619 is closer to 0 making it greater than -2.74 but less than -2.35 bc -2.35 is closer to 0 than -2.35619 is so.... (the greater the negative number, the less value it has)

-2.74 < -3pi/4 < -2.35

hope this helps ^_^
