Answer:
735/420 + 2 = 735/420 + 420/420 = 1155/420
Explanation:
To add the three fractions, we need to find a common denominator. A common denominator for all three fractions is 420:
30/15 = 2
25/40 = 25/40 * 3/3 = 75/120
30/35 = 30/35 * 12/12 = 360/420
Adding the three fractions with the common denominator:
2 + 75/120 + 360/420 = 2 + 375/420 + 360/420
Combining like terms:
2 + 735/420 = 2 + 735/420
The answer is 735/420 + 2 = 735/420 + 420/420 = 1155/420.
