The movement

Find the Least Common Denominator. Then, express each fraction using the Least Common Denominator.
7/10 and 5/6

Answer 1

To find the Least common denominator (LCD) of 7/10 and 5/6, we need to find the Least common multiple of 10 and 6.

I found the LCM through division method. Refer to image attached~

We can tell that:

• The LCM is 2 x 3 x 5, which when simplified, we obtain 30.
• The LCD is 30.

Now, let's multiply the denominators and the numerators such that 30 is the denominator in both fractions.

• => 7/10 = 7 x 3/10 x 3 = 21/30
• => 5/6 = 5 x 5/6 x 5 = 25/30

The fractions are:

• 21/30 and 25/30

Answer 2

LCM of 7/10- 70

LCM of 5/6- 30
