Question

3 7/8-2 3/4+1/2 3 5/14-1-6/7

Answer 1

3 7/8-2 3/4+1/2=3 7/8-2 6/8+4/8=1 1/8+4/8=1 5/8
3 5/14-1-6/7=3 5/14-1-12/14=2 5/14-12/14=1 19/14-12/14=1 7/14= 1 1/2

Answer 2

To solve this problem, we'll need to convert all the mixed numbers into improper fractions. Then we can perform the addition and subtraction operations and simplify the result.

3 7/8 can be written as (8*3 + 7)/8 = 31/8

2 3/4 can be written as (4*2 + 3)/4 = 11/4

1/2 is already in fraction form

3 5/14 can be written as (14*3 + 5)/14 = 47/14

1 can be written as 14/14

6/7 can't be simplified further.

Now we can substitute all these values in the expression and simplify:

31/8 - 11/4 + 1/2 + 47/14 - 14/14 - 6/7

First, let's simplify the mixed numbers into fractions:

31/8 - 11/4 + 1/2 + 47/14 - 14/14 - 6/7 = 31/8 - 22/4 + 1/2 + 47/14 - 14/14 - 6/7

Next, we can find a common denominator for all the fractions:

31/8 - 22/4 + 1/2 + 47/14 - 14/14 - 6/7 = 31/8 - 44/8 + 4/8 + 47/14 - 14/14 - 12/14

Now we can add and subtract the fractions:

31/8 - 44/8 + 4/8 + 47/14 - 14/14 - 12/14 = (31 - 44 + 4)/8 + (47 - 14 - 12)/14 = -9/8 + 21/14

We can simplify the fractions by finding a common denominator:

-9/8 + 21/14 = -99/56 + 42/56 = -57/56

Therefore, the final answer is -57/56.
