Answer 2

To solve the given expression, let's break it down step-by-step:

Step 1: Add the numbers on the left side of the equation: 3.3 + 12/25

Step 2: Convert the whole number (3.3) to a fraction: 3.3 = 3 + 0.3 = 3 + 3/10 = 30/10 + 3/10 = 33/10

Now, the expression becomes: 33/10 + 12/25

Step 3: Find a common denominator for the fractions. The least common multiple (LCM) of 10 and 25 is 50. So, we'll rewrite the fractions with a common denominator of 50:

33/10 = (33/10) * (5/5) = 165/50 12/25 = (12/25) * (2/2) = 24/50

Now, the expression becomes: 165/50 + 24/50

Step 4: Add the fractions: (165 + 24) / 50 = 189 / 50

Step 5: Simplify the fraction, if possible. In this case, both the numerator and denominator can be divided by 3: 189 ÷ 3 = 63 50 ÷ 3 = 16 2/3

So, the simplified fraction is: 63/16 2/3

However, we can still convert the mixed fraction to an improper fraction: 16 2/3 = (16 * 3 + 2) / 3 = 50/3

The final result is: 63/50 + 50/3

To combine the fractions, find a common denominator (LCM of 50 and 3, which is 150): 63/50 = (63/50) * (3/3) = 189/150 50/3 = (50/3) * (50/50) = 250/150

Now, the expression becomes: 189/150 + 250/150

Step 6: Add the fractions: (189 + 250) / 150 = 439 / 150

So, the final result of the expression is: 439/150
