Question

3 1/7- 1 9/14................."......

Answer 1

1) 22/7-23/14=44/14-23/14=19/14=1 5/14

Answer 2

To subtract the fractions 3 1/7 and 1 9/14, we need to convert them to a common denominator.

First, let's convert 3 1/7 to an improper fraction:

3 1/7 = (3 * 7 + 1) / 7 = 22/7

Next, let's convert 1 9/14 to an improper fraction:

1 9/14 = (1 * 14 + 9) / 14 = 23/14

Now that both fractions have a common denominator of 14, we can subtract them:

22/7 - 23/14

To subtract fractions, we need to find a common denominator. In this case, the common denominator is 14.

Let's proceed with the subtraction:

(22/7) - (23/14)

To subtract fractions, we need to have the same denominator. Since the first fraction already has a denominator of 7, we need to multiply the numerator and denominator of the second fraction by 2 to get the same denominator:

(22/7) - (23/14) = (22/7) - (23 * 2)/(14 * 2) = 22/7 - 46/28

Now that both fractions have the same denominator, we can subtract the numerators:

22/7 - 46/28 = (22 - 46)/28

Simplifying the numerator:

22 - 46 = -24

The result is -24/28, but we can simplify it by dividing both the numerator and denominator by their greatest common divisor, which is 4:

(-24/4) / (28/4) = -6/7

So, the subtraction of 3 1/7 and 1 9/14 is equal to -6/7.
