Find an equivalent fraction with the lowest common denominator.

9/10+2/3

Step-by-step explanation:

9/10+2/3

The LCM = 30

9/10+2/3

= {9 (3) + 2 (10) }/30

= (27 + 20) / 30

= 47/30

= 1 17/30

Answer: 1-17/30, or 47/30

Step-by-step explanation:

Find the common denominator. In this case, it's 30. Multiply the numerators to fit the new denominator. (10•3=30, so 9•3=27, and 2•10=20.)

Your new fractions are 27/30 and 20/30. Now add the numerators.

27+20=47.

Your new fraction is 47/30.

Now check if you can simplify. Since 47 is a prime number, this fraction is in its simplest form. However, it is an improper fraction, so you can simplify it to 1-17/30.
