1/2 divided by 1.9 minus 4 1/5
To solve this, we first convert the mixed numbers to improper fractions.
1/2 = 1/21.9 = 19/104 1/5 = 21/5
Now we can perform the division and subtraction:
1/2 ÷ 19/10 = 1/2 * 10/19 = 10/38 = 5/19
5/19 - 21/5 = (55 - 2119) / (19*5) = (25 - 399) / 95 = -374/95
Therefore, the result of the expression is -374/95.
