Answer 2

Let's solve the given expression step by step:

1. 3¾ + 2¼ - 3⅙

First, we'll convert all the mixed numbers to improper fractions for easier calculations:

• 3¾ = 3 + ¾ = 3 + 3/4 = 12/4 + 3/4 = 15/4
• 2¼ = 2 + ¼ = 2 + 2/4 = 8/4 + 2/4 = 10/4
• 3⅙ = 3 + 1/6 = 18/6 + 1/6 = 19/6

Now the expression becomes:

15/4 + 10/4 - 19/6

Now, let's find a common denominator for the fractions, which is the least common multiple of 4 and 6, which is 12.

Converting the fractions to have a denominator of 12:

• 15/4 * 3/3 = 45/12
• 10/4 * 3/3 = 30/12
• 19/6 * 2/2 = 38/12

Now the expression becomes:

45/12 + 30/12 - 38/12

Combining the fractions:

(45 + 30 - 38)/12 = 37/12

Now, we can convert the improper fraction back to a mixed number:

37/12 = 3 1/12

So, the answer is 3 1/12.

Out of the options provided: а) 2 ⅚ б) 3⅙ В) 1⅚ Г) 2⅜

None of the provided options match the result of 3 1/12.
