Question

Multiply, rational numbers practice

Answer 1

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
