Answer 2

2 7/30+3 9/20-4 59/60=-4,8

Answer 3

To solve the given expression, we need to add and subtract the mixed numbers separately. Let's break it down step by step:

2 7/30 + 3 9/20 - 4 59/60

Step 1: Convert the mixed numbers to improper fractions. 2 7/30 = (2 * 30 + 7) / 30 = 67/30 3 9/20 = (3 * 20 + 9) / 20 = 69/20 4 59/60 = (4 * 60 + 59) / 60 = 299/60

Step 2: Perform addition and subtraction of the fractions. 67/30 + 69/20 - 299/60

Step 3: Find a common denominator for the fractions. The least common multiple (LCM) of 30, 20, and 60 is 60. Therefore, we need to convert all the fractions to have a denominator of 60.

67/30 * 2/2 = 134/60 69/20 * 3/3 = 207/60 299/60 * 1/1 = 299/60

Step 4: Perform the addition and subtraction. 134/60 + 207/60 - 299/60

(134 + 207 - 299) / 60 42/60

Step 5: Simplify the fraction. 42/60 can be simplified by dividing both the numerator and denominator by their greatest common divisor (GCD), which is 6. 42/60 = (42/6) / (60/6) = 7/10

Therefore, 2 7/30 + 3 9/20 - 4 59/60 equals 7/10.
