I. 1.875
II. 11.25
III. 78.125
IV. 156.5
V. 241.5

Answer 1

To multiply fractions, multiply the numerators together and the denominators together. Divide the numerator by the denominator to simplify the result if possible.

Step-by-step explanation:

When multiplying fractions, you multiply the numerators together and the denominators together. Then, simplify the resulting fraction by dividing the numerator by the denominator if possible.

Let's use this method to solve the given problem:

1. 1/8 multiplied by 15/1 equals (1x15)/(8x1) = 15/8 = 1.875 (I. 1.875)
2. 1/4 multiplied by 45/1 equals (1x45)/(4x1) = 45/4 = 11.25 (II. 11.25)
3. 2/5 multiplied by 156.25/1 equals (2x156.25)/(5x1) = 312.5/5 = 78.125 (III. 78.125)
4. 3/2 multiplied by 104.5/1 equals (3x104.5)/(2x1) = 313.5/2 = 156.75 (IV. 156.5)
5. 3/4 multiplied by 322/1 equals (3x322)/(4x1) = 966/4 = 241.5 (V. 241.5)
6. 4/9 multiplied by 188.375/1 equals (4x188.375)/(9x1) = 753.5/9 = 83.722222 (VI. 472.0625)
