Answer 3

To subtract the given mixed numbers, follow these steps:

Step 1: Convert mixed numbers to improper fractions.

3 5/14 as an improper fraction: 3 * 14 + 5 = 42 + 5 = 47 So, 3 5/14 as an improper fraction is 47/14.

6/7 is already a fraction, so no conversion is needed.

Step 2: Subtract the fractions.

47/14 - 1 = 47/14 - 14/14 = (47 - 14)/14 = 33/14

Step 3: Subtract the remaining fraction from the result of step 2.

33/14 - 6/7

To subtract these fractions with different denominators, you need to find a common denominator, which in this case is 14 * 7 = 98.

Now, you can rewrite both fractions with the common denominator:

(33/14) * (7/7) - (6/7) * (14/14)

(231/98) - (84/98)

Step 4: Subtract the fractions with the common denominator.

(231/98) - (84/98) = (231 - 84)/98 = 147/98

Step 5: Simplify the fraction, if possible.

Both 147 and 98 can be divided by 7:

(147/7) / (98/7) = 21/14

Step 6: Further simplify if necessary.

21/14 can be simplified by dividing both the numerator and denominator by 7:

(21/7) / (14/7) = 3/2

So, 3 5/14 - 1 - 6/7 = 3/2.
