if you want an "exact" you will have to use only fractions

2 2/7 minus 1.75
= 16/7 - 7/4
= 64/28 - 49/8
= 15/28

Let's change the decimal to a fraction.

1.75 = 1 3/4

Next we need a common denominator -- which is 28.

2 2/7 = 2 8/28
1 3/4 = 1 21/28

2 8/28 - 1 21/28 = 1 36/28 - 1 21/28 = 15/28

To subtract 1.75 from 2 2/7, we can follow these steps:

Step 1: Convert the mixed number 2 2/7 to an improper fraction.
To convert a mixed number to an improper fraction, multiply the whole number by the denominator of the fraction and add the numerator. This gives us:
2 * 7 + 2 = 14 + 2 = 16
So, 2 2/7 can be written as the improper fraction 16/7.

Step 2: Subtract 1.75 from 16/7.
To subtract fractions or mixed numbers, we need to find a common denominator. In this case, the common denominator is 7. We don't need to convert 1.75 since it is already expressed as a decimal.

Step 3: Subtract the numerators and keep the common denominator.
16/7 - 1.75 can be written as (16 - (1.75 * 7))/7.

Step 4: Perform the calculation.
To calculate (16 - (1.75 * 7)), we multiply 1.75 by 7 and subtract the result from 16. This gives us:
(16 - (1.75 * 7)) = (16 - 12.25) = 3.75

Step 5: Simplify the result.
The final expression is 3.75/7.

Therefore, the answer to 2 2/7 minus 1.75 is 3.75/7 or simply 3 3/4.
