Question

Which of these numbers are integers? Choose ALL the integers.

a. 1
b. 5
c. 5.
d. 0.2
e. 21
f. -2
g. -11.5

Answer 1

The integers from the provided options are 1, 5 (if 5. is considered as a typo for 5), 21, and -2. Decimal numbers like 0.2 and -11.5 are not considered integers.

Step-by-step explanation:

The question asks which of the following numbers are integers: 1, 5, 5., 0.2, 21, -2, -11.5. Integers are whole numbers that can be positive, negative, or zero, but do not include fractions or decimals. Using this definition, we can identify that the integers from the options provided are:

• 1
• 5
• 5. - This is not a number in standard form and seems to be a typo or an irrelevant part, but if interpreted as 5, it is an integer.
• 0.2 - This is not an integer since it's a decimal number.
• 21
• -2
• -11.5 - This is not an integer because it's a decimal number.
