Question

18/85+6целых 5/68-7/17

Answer 1

18/85+413/68-7/17= 72/340+2065/340-140/340= 1997/340= 5 297/340

Answer 2

To solve the expression, let's start by converting the mixed numbers into improper fractions:

6 целых = 6 5/68 = 5/68 7/17 = 7/17

Now, the expression becomes:

18/85 + 6 + 5/68 - 7/17

Next, we need to find a common denominator for all fractions, which is 85 * 68 * 17 = 97820. Now, we can rewrite each fraction with the common denominator:

(18 * 68 * 17) / 97820 + (6 * 97820) / 97820 + (5 * 85 * 17) / 97820 - (7 * 85 * 68) / 97820

Now, let's calculate each part:

= (20736 + 586920 + 7225 - 326340) / 97820 = (296541) / 97820

Now, we can simplify the fraction. The greatest common divisor (GCD) of 296541 and 97820 is 1, so the fraction is already in its simplest form.

The final result is approximately 3.03366177946 (rounded to 11 decimal places).
