42/9+31/3 simplify... help please

Which is it?

42/9+31/3
or
4 2/9 + 3 1/3

31/3 = 4 6/9 which breaks down to 4 2/3

42/9 = 10 1/3
4 2/3 + 10 1/3 = 14 3/3 = 15

To simplify the expression (42/9) + (31/3), you first need to find a common denominator for the fractions. The common denominator is the least common multiple (LCM) of 9 and 3, which is 9.

Now, you can convert both fractions to have a denominator of 9:

(42/9) = (42 * 1)/ (9 * 1) = 42/9
(31/3) = (31 * 3) / (3 * 3) = 93/9

Now that the fractions have the same denominator, you can add them together:

(42/9) + (31/3) = (42 + 93)/9 = 135/9

The resulting fraction, 135/9, can be simplified further. It is equivalent to 15/1, which can be written as the whole number 15.
