Question

integer?
yes no
19.12
62
$-dfrac{7}{7}$
$-dfrac{2}{3}$
55

Explanation:

Step1: Analyze 19.12

Integers are whole numbers (positive, negative, or zero) without a fractional or decimal part. 19.12 has a decimal part, so it's not an integer.

Step2: Analyze 62

62 is a whole number with no fractional or decimal part, so it is an integer.

Step3: Analyze \(-\frac{7}{7}\)

Simplify \(-\frac{7}{7} = - 1\), which is a whole number (integer).

Step4: Analyze \(-\frac{2}{3}\)

\(-\frac{2}{3}\) is a fraction (rational number but not an integer) as it represents a part of a whole and is not a whole number.

Step5: Analyze 55

55 is a whole number with no fractional or decimal part, so it is an integer.

Answer:

For 19.12: No
For 62: Yes
For \(-\frac{7}{7}\): Yes
For \(-\frac{2}{3}\): No
For 55: Yes
