This can be understood as the sum of the whole number 80 and the fraction 9\/20. The whole number, 80, will form the part of the decimal that is to the left of the decimal point. Our main task is to convert the fraction 9\/20 into its decimal form.<\/p>\n\n\n\n<p>There are two primary methods to convert a fraction to a decimal.<\/p>\n\n\n\n<p>The first method involves finding an equivalent fraction with a denominator that is a power of 10 (like 10, 100, 1000, etc.). This is often the simplest approach if the denominator can be easily converted. For the fraction 9\/20, we can see that the denominator, 20, can be multiplied by 5 to get 100. To ensure the value of the fraction remains the same, we must also multiply the numerator, 9, by the same factor of 5.<\/p>\n\n\n\n<p>So, the calculation for the equivalent fraction is:<br>(9 \u00d7 5) \/ (20 \u00d7 5) = 45\/100<\/p>\n\n\n\n<p>The fraction 45\/100 is read as &#8220;forty-five hundredths,&#8221; which directly translates to the decimal 0.45.<\/p>\n\n\n\n<p>The second method is to perform division. A fraction represents a division problem where the numerator is divided by the denominator. In this case, we would divide 9 by 20.<\/p>\n\n\n\n<p>9 \u00f7 20 = 0.45<\/p>\n\n\n\n<p>Both methods yield the same result: the fractional part 9\/20 is equal to 0.45.<\/p>\n\n\n\n<p>Finally, we combine the whole number part with the decimal part. We add the whole number 80 to the decimal 0.45:<\/p>\n\n\n\n<p>80 + 0.45 = 80.45<\/p>\n\n\n\n<p>Therefore, the mixed number 80 9\/20 is equivalent to the decimal number 80.45.<\/p>\n\n\n\n<figure class=\"wp-block-image size-full\"><img decoding=\"async\" src=\"https:\/\/learnexams.com\/blog\/wp-content\/uploads\/2025\/08\/learnexams-banner5-340.jpeg\" alt=\"\" class=\"wp-image-281114\"\/><\/figure>\n","protected":false},"excerpt":{"rendered":"<p>The Correct Answer and Explanation is: 80.45 To write the mixed number 80 9\/20 as a decimal, we need to address both the whole number part and the fractional part separately and then combine them.
