It is a simple question on decimal conversion. Firstly, we have to learn fractions and decimals. A fraction represents a part of a whole. It has two parts: the numerator (number on the top), here 1, represents how many parts out of the whole. The denominator (number below) shows how many parts make the whole, here it is 4. A decimal is a way to represent a number that is not whole, using a (.) or a decimal to separate the whole part from the fraction part. The numbers to the left of the decimal point represent the whole, and those to the right represent the fractional part.

$20 1/4 as a decimal$

Answer

20 1/4 in decimals can be written as 20.25. It is a terminating decimal and does not repeat.

Explanation

To convert 20 1/4 to a decimal, we separate the whole number and the fraction. The whole number is 20, and the fraction is 1/4. To convert the fraction to a decimal, we divide the numerator by the denominator.

Step 1: Identify the numerator and denominator of the fraction. The numerator (1) is the dividend, and the denominator (4) is the divisor.

Step 2: Divide 1 by 4, which gives 0.25.

Step 3: Combine the whole number and the decimal fraction: 20 + 0.25 = 20.25.

Thus, 20 1/4 as a decimal is 20.25.
