Multiply, rational numbers practice
Sure! Here are a few examples to help you practice multiplying rational numbers:
Example 1:
Multiply: (3/5) * (4/7)
Solution: To multiply two fractions, you simply multiply the numerators and denominators separately. Therefore, (3/5) * (4/7) = (3 * 4) / (5 * 7) = 12/35
Example 2:
Multiply: (-2/3) * (5/8)
Solution: (-2/3) * (5/8) = (-2 * 5) / (3 * 8) = -10/24 = -5/12
Example 3:
Multiply: (1/2) * (3)
Solution: When multiplying a rational number by a whole number, you can consider the whole number as a fraction with a denominator of 1. Therefore, (1/2) * (3/1) = (1 * 3) / (2 * 1) = 3/2
Example 4:
Multiply: (-7/9) * (-2/5)
Solution: When multiplying two negative fractions, the result becomes positive. Therefore, (-7/9) * (-2/5) = (7/9) * (2/5) = (7 * 2) / (9 * 5) = 14/45
Hope this helps! Let me know if you have any further questions.
Sure! I can help you practice multiplying rational numbers step-by-step.
Step 1: Understand the problem
Before solving a problem involving multiplying rational numbers, it's important to understand what rational numbers are. Rational numbers are any numbers that can be expressed as a fraction, where the numerator and denominator are integers.
Step 2: Write down the problem
Let's say we're given the following multiplication problem: (1/4) * (3/8). We want to find the product of these two rational numbers.
Step 3: Simplify the fractions (if necessary)
In this case, the fractions are already in their simplified forms. If the fractions were not already simplified, we would need to simplify them first. This involves finding the greatest common divisor (GCD) of the numerator and denominator and dividing both the numerator and denominator by this GCD.
Step 4: Multiply the numerators
To multiply the two fractions, we simply multiply the numerators together. In this case, 1 * 3 = 3.
Step 5: Multiply the denominators
Similarly, we multiply the denominators together. In this case, 4 * 8 = 32.
Step 6: Write down the product
The product of the two fractions is 3/32.
Step 7: Simplify the product (if necessary)
In this case, the product 3/32 is already in its simplest form. If the product was not simplified, we would need to simplify it by finding the GCD of the numerator and denominator and dividing both by the GCD.
So, the final answer to the problem (1/4) * (3/8) is 3/32.
