Question

1-1/3. 1-3/7. 1-8/8. 1-3/27

Answer 1

2/3. 4/7. 0. 24/27=8/9

Answer 2

Представим 1 как 3/3, 
1 - 1/3 = 3/3 - 1/3 = 2/3
аналогично:
1 - 3/7 = 7/7 - 3/7 = 4/7
1 - 8/8 = 8/8 - 8/8 = 0
1 - 3/27 = 27/27 - 3/27 = 24/27

Answer 3

To solve the given expressions, let's simplify each one:

1. 1 - 1/3: To subtract fractions, we need a common denominator. The common denominator of 3 is 3 itself. So, (1/3) is equivalent to (1/3) * (3/3) = 3/9. Now, we can subtract: 1 - 3/9 = 9/9 - 3/9 = 6/9. The simplified result is 6/9, which can be further simplified to 2/3.

2. 1 - 3/7: Again, we need a common denominator to subtract fractions. The common denominator of 7 is 7 itself. So, (3/7) is equivalent to (3/7) * (7/7) = 21/49. Now, we can subtract: 1 - 21/49 = 49/49 - 21/49 = 28/49. The simplified result is 28/49, which can be further simplified to 4/7.

3. 1 - 8/8: Since the numerator and denominator are the same, 8/8 is equal to 1. Therefore, 1 - 8/8 = 1 - 1 = 0.

4. 1 - 3/27: To subtract fractions, we need a common denominator. The common denominator of 27 is 27 itself. So, (3/27) is equivalent to (3/27) * (27/27) = 81/729. Now, we can subtract: 1 - 81/729 = 729/729 - 81/729 = 648/729. The simplified result is 648/729, which can be further simplified. Both the numerator and denominator are divisible by 9, so dividing them by 9 yields 72/81. Simplifying further, we get 8/9.

In summary: 1-1/3 = 2/3 1-3/7 = 4/7 1-8/8 = 0 1-3/27 = 8/9
