Using conversions of mixed numbers, the numbers that are equivalent to 2 and 7/9 are given by:

25/9 and 2.777.

<h3>What are the conversions of the mixed number 2 and 7/9?</h3>

To convert to decimal, we just add the integer part with the fractional part converted to decimal(dividing the numerator by the denominator), hence:

2 and 7/9 = 2 + 7/9 = 2.7777.

To convert to fraction, the procedure is similar, we just apply the least common multiple to add the fraction, as follows:

2 + \frac{7}{9} = \frac{2 \times 9 + 7}{9} = \frac{25}{9}

Hence the numbers that are equivalent to 2 and 7/9 are given by:

25/9 and 2.777.
