The negative sign applies to the entire number, so we will first find the decimal for 30 19\/40 and then apply the negative sign to the final result.<\/p>\n\n\n\n<p>The number consists of the whole number 30 and the fraction 19\/40. The whole number 30 will be the part of the decimal number to the left of the decimal point. Our main task is to convert the fractional part, 19\/40, into its decimal equivalent.<\/p>\n\n\n\n<p>To convert a fraction to a decimal, you divide the numerator by the denominator. In this case, we need to perform the division 19 \u00f7 40.<\/p>\n\n\n\n<p>We can set up a long division:<\/p>\n\n\n\n<ol class=\"wp-block-list\">\n<li>Since 19 is smaller than 40, the result will be less than 1. We place a decimal point and add a zero to 19, making it 190.<\/li>\n\n\n\n<li>We ask how many times 40 goes into 190. It goes in 4 times (4 \u00d7 40 = 160). We write down &#8220;4&#8221; as the first digit after the decimal point. The remainder is 190 &#8211; 160 = 30.<\/li>\n\n\n\n<li>We bring down another zero to our remainder, making it 300. Now we ask how many times 40 goes into 300. It goes in 7 times (7 \u00d7 40 = 280). We write down &#8220;7&#8221; as the next digit. The remainder is 300 &#8211; 280 = 20.<\/li>\n\n\n\n<li>We bring down a final zero, making the number 200. We ask how many times 40 goes into 200. It goes in exactly 5 times (5 \u00d7 40 = 200). We write down &#8220;5&#8221; as the last digit. The remainder is now 0, so the division is complete.<\/li>\n<\/ol>\n\n\n\n<p>So, the fraction 19\/40 is equal to the decimal 0.475.<\/p>\n\n\n\n<p>Now, we combine the whole number part (30) with the decimal part (0.475). This gives us 30.475.<\/p>\n\n\n\n<p>Finally, we reapply the negative sign from the original mixed number. Therefore, -30 19\/40 as a decimal is -30.475.<\/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-banner5-141.jpeg\" alt=\"\" class=\"wp-image-279148\"\/><\/figure>\n","protected":false},"excerpt":{"rendered":"<p>The Correct Answer and Explanation is: -30.475 To convert the mixed number -30 19\/40 into a decimal, we need to handle the whole number part and the fractional part separately.
