Identify the number as a regional or irrational.explain. 291.87
Ugo [173]

Answer:

291.87 is a rational number.

Step-by-step explanation:

Rational numbers are those numbers that can be expressed in fractions that is can be written as \frac{p}{q} where p and q are integers and q\neq 0.

Consider the given number 291.87

Rewrite the decimal number as a fraction with 1 in the denominator, we get,

291.87=\frac{291.87}{1}

Multiply to remove 2 decimal places. Here, you multiply top and bottom by 10² = 100

\frac{291.87}{1}=\frac{29187}{100}

Thus, the above fraction can be written as,

\frac{29187}{100}=291\frac{87}{100}

Thus, 291.87 is a rational number.
