To multiply a fraction by a whole number, you can use the following steps:

1. Multiply the numerator of the fraction by the whole number: Take the numerator of the fraction and multiply it by the whole number.

2. Keep the denominator the same: The denominator of the fraction remains the same.

For example, to multiply the fraction 1/2 by the whole number 3, you would do the following:

1. Multiply the numerator (1) by the whole number (3): 1 x 3 = 3
2. Keep the denominator the same (2)

The result is the fraction 3/2.

So, the general formula is:

(a/b) x c = (a x c) / b

Where:

• a is the numerator of the fraction
• b is the denominator of the fraction
• c is the whole number
