1 1/5 as a Decimal

Answer

1 1/5 in decimal form can be written as 1.2. It is a terminating decimal, meaning it ends after a finite number of digits.

Explanation

To convert 1 1/5 into a decimal, we will use the division method for the fractional part. The mixed number consists of a whole number (1) and a fraction (1/5). Let's see the step-by-step breakdown of the process:

Step 1: Identify the whole number and the fraction. The whole number is 1, and the fraction is 1/5.

Step 2: Convert the fraction 1/5 into a decimal. The numerator (1) will be taken as the dividend, and the denominator (5) will be taken as the divisor.

Step 3: Divide 1 by 5. Since 1 is smaller than 5, we add a decimal point and a zero to make it 10.

Step 4: Divide 10 by 5, which gives 2. Write 2 to the right of the decimal point.

Step 5: Combine the whole number with the decimal.

The whole number is 1, and the decimal from the fraction is 0.2, resulting in 1.2.

• Fraction: A numerical quantity that is not a whole number, representing a part of a whole.

• Decimal: A number that uses the base ten and includes a decimal point to separate the whole part from the fractional part.

• Mixed Number: A number consisting of a whole number and a fraction. Terminating Decimal: A decimal that ends and does not repeat infinitely.

• Division: A mathematical operation where one number, the dividend, is divided by another, the divisor, to find how many times the divisor fits into the dividend.
