5 1/2 * 3/4
= (11/2)(3/4)
= 33/4 , which is reduced to lowest terms
Thank u so much, this is the 1st lesson in this class, and my 1st math lesson in college period, and im 26, so im a little out of the loop and extremely confused when it comes to math. Thank u so much. Would u mind explaining it to me pls?!
How do you think Reiny and I got 11/2 from 5 1/2?
From there we multiplied the two numerators together and the two denominators together.
To multiply and reduce the fractions 5 1/2 and 3/4, follow these steps:
Step 1: Convert the mixed number 5 1/2 to an improper fraction:
To do this, multiply the whole number (5) by the denominator (2) and add the numerator (1) to the result. So, it becomes:
5 * 2 + 1 = 10 + 1 = 11
Rewriting it as an improper fraction, we get 11/2.
Step 2: Multiply the numerators and denominators of the fractions:
Multiply the numerators (11 and 3) together, and multiply the denominators (2 and 4) together. Perform the multiplication as follows:
11/2 * 3/4 = (11 * 3) / (2 * 4) = 33/8
Step 3: Reduce the fraction to its lowest terms:
To reduce a fraction to its lowest terms, find the greatest common divisor (GCD) of the numerator and denominator and divide them both by it.
The GCD of 33 and 8 is 1, so divide both 33 and 8 by 1:
33 ÷ 1 = 33
8 ÷ 1 = 8
Therefore, the reduced fraction is 33/8.
Thus, the result of multiplying and reducing 5 1/2 by 3/4 is 33/8.
