Question

1) 1 целая 7/12 : (3/8 + 5/12)= 2) 17/36 : (7/12 - 5/9)=Решите пожалуйста умоляю дам 30 баллов!

Answer 1

1) = 19/12 : 19/24= 19/12 * 24/19 = 24/12 = 2
2) = 17/36 : (21/36- 20/36) = 17/36 * 36 = 17

Answer 2

1) будет ответ 2, 3/8+5/12 будет 19/24, а после делим 7/12 на 19/24 будет 2 2) будет ответ 17, 7/12-5/9 будет 1/36, а после делим 17/36 на 1/36 будет 17 На будущее скажу: сначало выполняет действие в скобках

Answer 3

1) To solve the equation 1 7/12 + (3/8 + 5/12), we need to find a common denominator for the fractions involved. The common denominator for 8, 12, and 12 is 24.

Converting the fractions to have a denominator of 24, we get: 1 7/12 = 24/24 + 14/24 = 38/24 3/8 = 9/24 5/12 = 10/24

Now we can add the fractions: 38/24 + (9/24 + 10/24) = 38/24 + 19/24 = 57/24

Simplifying the fraction, we have: 57/24 = 2 9/24 = 2 3/8

Therefore, 1 7/12 + (3/8 + 5/12) equals 2 3/8.

2) To solve the equation 17/36 + (7/12 - 5/9), we need to find a common denominator for the fractions involved. The common denominator for 36, 12, and 9 is 36.

Converting the fractions to have a denominator of 36, we get: 17/36 = 17/36 7/12 = 21/36 5/9 = 20/36

Now we can subtract the fractions: 17/36 + (21/36 - 20/36) = 17/36 + 1/36 = 18/36

Simplifying the fraction, we have: 18/36 = 1/2

Therefore, 17/36 + (7/12 - 5/9) equals 1/2.

I hope this helps! Let me know if you have any further questions.
