Answer 2

Let's solve the expression step by step:

Step 1: Simplify the fraction (11/59 - 1/9 + 5/18) To do this, we need to find a common denominator for the fractions. The common denominator for 59, 9, and 18 is 5318. Now, we can rewrite the expression with the common denominator:

(11/59) - (1/9) + (5/18) = (115318)/(595318) - (15318)/(95318) + (55318)/(185318)

Step 2: Perform the arithmetic operations for the fractions:

= 58798/313162 - 5318/47862 + 26590/95628

Step 3: Find a common denominator for the result from Step 2 (313162 * 47862 * 95628 = 1,509,348,808,396)

Now, we can rewrite the expression with the common denominator:

= (58798 * 47862 * 95628)/(313162 * 47862 * 95628) - (5318 * 313162 * 95628)/(47862 * 313162 * 95628) + (26590 * 313162 * 47862)/(95628 * 313162 * 47862)

Step 4: Perform the arithmetic operations for the numerators:

= 26685677343376/1,509,348,808,396 - 1606749749352/1,509,348,808,396 + 1268782357080/1,509,348,808,396

Step 5: Combine the fractions with the same denominator:

= (26685677343376 - 1606749749352 + 1268782357080)/1,509,348,808,396

Step 6: Perform the addition:

= 27420457415304/1,509,348,808,396

Step 7: Now, multiply the result by 0.75:

= (27420457415304/1,509,348,808,396) * 0.75

Step 8: Perform the multiplication:

= 20565343061428/1,509,348,808,396

Step 9: Finally, add 0.25 to the result:

= 20565343061428/1,509,348,808,396 + 0.25

The result of the expression is approximately 0.2568.
