Обчисліть: 1)1 - 16/23; 2)5 - 7/16; 3)6 - 1 3/5; 4)8 - 7 12/25

Answer 1

Ответ:

1)7/23

2)4 9/16

3)4 2/5

4)13/25

Пошаговое объяснение:

1)1-16/23= 23/23-16/23=7/23

2)5-7/16=4 16/16-7/16=9/16

3)6-1 3/5= 5 5/5-1 3/5=4 2/5

4)8-7 12/25=7 25/25-7 12/25= 13/25

Answer 2

1. To calculate 1 - 16/23, we need to find a common denominator for 1 and 16/23. The common denominator is 23, so we can rewrite 1 as 23/23.

Now we can subtract the fractions:

23/23 - 16/23 = (23 - 16)/23 = 7/23

Therefore, 1 - 16/23 is equal to 7/23.

2. To calculate 5 - 7/16, we need to find a common denominator for 5 and 7/16. The common denominator is 16, so we can rewrite 5 as 80/16.

Now we can subtract the fractions:

80/16 - 7/16 = (80 - 7)/16 = 73/16

Therefore, 5 - 7/16 is equal to 73/16.

3. To calculate 6 - 1 3/5, we need to convert the mixed number 1 3/5 into an improper fraction. To do this, we multiply the whole number (1) by the denominator (5) and add the numerator (3). This gives us 8/5.

Now we can subtract the fractions:

6 - 8/5 = (6 * 5 - 8)/5 = (30 - 8)/5 = 22/5

Therefore, 6 - 1 3/5 is equal to 22/5.

4. To calculate 8 - 7 12/25, we need to convert the mixed number 7 12/25 into an improper fraction. To do this, we multiply the whole number (7) by the denominator (25) and add the numerator (12). This gives us 187/25.

Now we can subtract the fractions:

8 - 187/25 = (8 * 25 - 187)/25 = (200 - 187)/25 = 13/25

Therefore, 8 - 7 12/25 is equal to 13/25.
