What is 2/3 -3/5 with 15 being a common denominator
To find a common denominator of 15, we need to find the least common multiple (LCM) of 3 and 5, which is 15.
Now, we have to convert both fractions with denominators of 3 and 5 to have a denominator of 15.
For 2/3, we can multiply the numerator and denominator by 5 to get: (2 * 5)/(3 * 5) = 10/15.
For 3/5, we can multiply the numerator and denominator by 3 to get: (3 * 3)/(5 * 3) = 9/15.
Now, we can subtract the two fractions: 10/15 - 9/15 = (10 - 9)/15 = 1/15.
Therefore, 2/3 - 3/5 with a common denominator of 15 is equal to 1/15.
