How do I simplify fractions and decimals?

Mila [183]

Answer:

Divide both the numerator and denominator by the largest number that divides evenly into both to simplify the fraction

In the example, divide 2 by 2, which equals 1, and divide 20 by 2, which equals 10. This leaves 1/10, which is the simplified form of the fraction with a decimal.

Answer:

<h2>C. 1,004.8 cubic units</h2>

Step-by-step explanation:

$V = ?\\r = 8\\h =5 \\\pi = 3.14\\\\V = \pi r^2 h\\\\V = 3.14 \times 8^2 \times 5\\V = 1004.8 cubic units$
