Multiply -1.7 by 2 1/2
To multiply -1.7 by 2 1/2, we can first convert the mixed number into an improper fraction.
2 1/2 = (2*2 + 1)/2 = 5/2
Now, we can multiply -1.7 by 5/2:
-1.7 * 5/2 = (-1.7 * 5) / 2 = -8.5 / 2
To simplify this fraction, we can divide both the numerator and denominator by their greatest common divisor, which is 1:
-8.5 / 2 = -4.25
To multiply -1.7 by 2 1/2, follow these steps:
Step 1: Convert the mixed number 2 1/2 to an improper fraction.
- Multiply the whole number (2) by the denominator (2), then add the numerator (1).
- In this case, 2 multiplied by 2 is 4, then add 1 to get 5.
- So, 2 1/2 is equal to 5/2 as an improper fraction.
Step 2: Multiply -1.7 by 5/2.
- Multiply the numerators (-1.7 × 5 = -8.5).
- Multiply the denominators (2 × 1 = 2).
- So, -1.7 multiplied by 2 1/2 is equal to -8.5/2.
The final answer is -8.5/2.
