To multiply -1.7 by 21/2, you can follow these steps:

Step 1: Convert the mixed number 21/2 to an improper fraction. The numerator of the improper fraction is obtained by multiplying the whole number (21) by the denominator (2), and then adding the numerator of the fraction (1). So, 21/2 becomes (21 * 2 + 1)/2, which is equal to 43/2.

Step 2: Multiply -1.7 by 43/2. To do this, you can multiply the numerators together (-1.7 * 43) and multiply the denominators together (2 * 1).

-1.7 * 43 = -73.1

2 * 1 = 2

Step 3: Simplify the result. Since the numerator is -73.1 and the denominator is 2, the final answer is -73.1/2.

Therefore, multiplying -1.7 by 21/2 is equal to -73.1/2.
