Direct link to Brenda Punio's post Hello i need help abou, Posted 10 years ago. can x plus 2 equal 0? A ratio greater than one means there are more job openings than people looking to work. So we have minus 1, minus 2, For less than you can use the <-sign. Because there are like denominators you can compare the numerators. We already know that numbers farther to the right on the number line are greater for positive numbers. while an inequality says that one expression is greater than, greater than or equal to, less than, or less than or equal to, another. this fraction going to be greater than 0? if there is a big portion of the graph shaded does that mean it's greater than or less than? Then, if you're dealing with two numbers, the result is positive if the signs of both numbers are the same, and the result is negative if the signs of both numbers are different.\nCheck out the following examples:\n\nSo, 8 multiplied by 2 is 16, and because the signs of both numbers are different, the answer is negative, 16.\n\nSo, 5 multiplied by 11 is 55, and because the signs of both numbers are the same, the result is positive, +55.\n\nSo, 24 divided by 3 is 8, and because both numbers have different signs, the result is negative, 8.\n\nSo, 30 divided by 2 is 15, and because both numbers have the same signs, the answer is positive, +15.\nWhen multiplying and dividing more than two positive and negative numbers, use the Even-Odd Rule: Count the number of negative signs if you have an even number of negatives, the result is positive, but if you have an odd number of negatives, the result is negative.\nThe following examples show you how to use the Even-Odd Rule:\n\nThis problem has just one negative sign. And that means that r equals 5 root 2. There is a chance that Z is less than.56 That gives us 1 - 1877. . And then we can multiply Fractions Calculator, 6 > x > 3. Direct link to inverse of infinity's post take the lcm and then mul. Positive numbers are bigger, greater, or higher than zero. We have a positive divided \( \dfrac{5}{6} \times \dfrac{4}{4} = \dfrac{20}{24} \), \( \dfrac{3}{8} \times \dfrac{3}{3} = \dfrac{9}{24} \), Compare integers, decimals, fractions, mixed, or percents, https://www.calculatorsoup.com/calculators/math/fractionscomparing.php, If you have mixed numbers convert them to improper fractions, Convert each fraction into its equivalent with the LCD in the denominator. what do the dotted and full lines stand for?
