Answer 1

Ответ:

(7/24-5/36) : 1 2/9

1) (7/24-5/36) = 21-10/72=11/72

2) 11/72:1 2/9 (сокращаем 2 и 72) = 11/36*1/9=11/324

Ответ: 11/324

Answer 2

(7/24 - 5/36) : 1 2/9  

1) 7/24 - 5/36 = 21/72 - 10/72 = 11/72

72 - наименьшее общее кратное

2) 11/72 : 1 2/9 = 11/72 : 11/9 = 11 * 9/ 72 * 11(сокращаем 11 на 11, получаем и там, и там 1; сокращаем 9 и 72 на 9, получаем 1 и 8) = 1/8

Ответ: 1/8.

Answer 3

Sure! Let's solve the expression step by step:

Step 1: Convert mixed numbers to improper fractions 7/24 = (7 * 1/24) = 7/24 5/36 = (5 * 1/36) = 5/36

Step 2: Subtract the fractions To subtract fractions, we need to have a common denominator. The least common multiple (LCM) of 24 and 36 is 72.

(7/24) - (5/36) = (7 * 3/3 * 1/24) - (5 * 2/2 * 1/36) = 21/72 - 10/72

Step 3: Subtract the numerators and keep the common denominator = (21 - 10)/72 = 11/72

Step 4: Convert the improper fraction to a mixed number (if desired) To convert the improper fraction to a mixed number, we divide the numerator by the denominator:

11 ÷ 72 = 0 remainder 11

The quotient (0) is the whole number, and the remainder (11) becomes the new numerator. The denominator remains the same.

So, the result is 0 11/72.
