(4 8/15-1 1/3)• 1 7/8

To solve this expression, we need to perform the subtraction first, then multiply the result by 1 7/8.

First, let's convert the mixed numbers into improper fractions.

4 8/15 = (415 + 8)/15 = 68/15 1 1/3 = (13 + 1)/3 = 4/3 1 7/8 = (1*8 + 7)/8 = 15/8

Now, the expression becomes: (68/15 - 4/3)• 15/8

To subtract fractions, we need a common denominator, which in this case is 15.

(68/15 - 4/3) = (68/15 - 20/15) = 48/15 = 16/5

Now the expression becomes: (16/5) • (15/8)

To multiply fractions, we simply multiply the numerators together and the denominators together:

(16/5) • (15/8) = (1615)/(58) = 240/40 = 6

Therefore, the result of the expression (4 8/15 - 1 1/3) • 1 7/8 is 6.
