Sure! Here's a step-by-step practice to add rational numbers:
Step 1: Identify the rational numbers that you want to add. Rational numbers are numbers that can be expressed as a fraction, where the numerator and denominator are integers.
Step 2: Check if the rational numbers have the same denominator. If they do, you can skip to step 4. If they don't, proceed to step 3.
Step 3: Find the least common multiple (LCM) of the denominators. The LCM is the smallest number that is divisible by both denominators. Once you have the LCM, you can use it as the common denominator to rewrite the fractions with the same denominator.
Step 4: Add the fractions together. To do this, add the numerators of the fractions and keep the same denominator.
Step 5: Simplify the resulting fraction, if necessary. If the numerator and denominator have a common factor, divide both by that factor to simplify the fraction.
Step 6: If the resulting fraction is an improper fraction (the numerator is larger than the denominator), you can convert it to a mixed number by dividing the numerator by the denominator. The quotient becomes the whole number part, and the remainder becomes the numerator of the fraction part.
Step 7: Write the final answer in the appropriate form, either as a simplified fraction, a mixed number, or a decimal, depending on the context.
Example: Let's add the rational numbers 1/4 and 3/8.
Step 1: Identify the rational numbers - 1/4 and 3/8.
Step 2: Check the denominators - both have different denominators, so proceed to step 3.
Step 3: Find the LCM of 4 and 8. In this case, the LCM is 8 since it is divisible by both 4 and 8.
Step 4: Rewrite the fractions with the common denominator of 8: 1/4 = 2/8 and 3/8 = 3/8.
Step 5: Add the fractions together: 2/8 + 3/8 = 5/8.
Step 6: The fraction is already simplified, so we don't need to do anything here.
Step 7: The final answer is 5/8.
I hope this practice helps! Let me know if you have any further questions.
To practice adding rational numbers, you can follow these steps:
Step 1: Convert the rational numbers, if necessary, so that they have the same denominator.
Step 2: Add the numerators together and write the sum over the common denominator.
Step 3: Simplify the fraction, if possible, by reducing it to the lowest terms.
Let's try an example:
Example: Add 2/3 and 5/6
Step 1: The denominators are already different, so we need to find a common denominator. The least common multiple (LCM) of 3 and 6 is 6.
Step 2: Now, we rewrite each fraction with the common denominator:
2/3 = 4/6 (we multiplied the numerator and denominator of the first fraction by 2)
5/6 (no change needed)
Step 3: We can now add the numerators together:
4/6 + 5/6 = 9/6
Step 4: To simplify the fraction, we can divide the numerator and denominator of 9/6 by their greatest common divisor, which is 3:
9/6 ÷ 3/3 = 3/2
So, the sum of 2/3 and 5/6 is 3/2.
