Math:Write 3/4 and 5/8 as a pair of fractions with common denominator
the LCM of 4 and 8 is 8
so 3/4 = 6/8
so you have 6/8 and 5/8
Now do what ever you want to do to them
thank you

To write 3/4 and 5/8 as a pair of fractions with a common denominator, you need to find the least common denominator (LCD) of both fractions.
The least common denominator is the smallest multiple that both denominators will divide into evenly. In this case, the denominators are 4 and 8.
To find the LCD, you can list the multiples of each denominator until you find a common multiple. For 4, the multiples are 4, 8, 12, 16, 20, ... and for 8, the multiples are 8, 16, 24, 32, 40, ...
From the lists above, you can see that the first common multiple is 8. Therefore, the LCD of 4 and 8 is 8.
Now, to convert 3/4 to a fraction with the denominator of 8, you need to multiply the numerator and denominator by 2 since 4 times 2 equals 8. So, 3/4 becomes (3 * 2) / (4 * 2) = 6/8.
Similarly, to convert 5/8 to a fraction with the denominator of 8, you can see that it already has the same denominator. So, no conversion is needed.
Therefore, the pair of fractions with common denominator 8 is 6/8 and 5/8.
