Answer 1

1) 2 2/5×2 7/9=12/5×25/9=4/1×5/3=20/3

2) 9-20/3=27/3-20/3=7/3=2 1/3

Answer 2

To solve the expression step by step, let's break it down:

1. Start with the multiplication: 2 2/5 • 2 7/9

   Convert the mixed numbers to improper fractions: 2 2/5 = (5 * 2 + 2)/5 = 12/5 2 7/9 = (9 * 2 + 7)/9 = 25/9

   Multiply the fractions: (12/5) • (25/9)

   Multiply the numerators (12 * 25) and the denominators (5 * 9): (12/5) • (25/9) = (300/45)

   Simplify the fraction: (300/45) = (20/3)

2. Now subtract: 9 - (20/3)

   Convert 9 to a fraction with a denominator of 3: 9 = (9 * 3/3) = (27/3)

   Subtract the fractions: (27/3) - (20/3) = (7/3)

   The result is 7/3.
