Question

8:10 2/3 9 5/7 : 1 23/28 1 2/15 : (3 7/9 - 2 3/7 )

Answer 1

Ответ:

Пошаговое объяснение:

8:10 2/3 = 8: 32/3 = 3/4

9 5/7 : 1 23/28 = 68/7 : 51/28 = (68*28)/(7*51) = (4*17*4*7)/(7*3*17) =16/3 = 5 1/3

1 2/15 : (3 7/9 - 2 3/7 ) = 17/15 : (34/9 + 17/7) = 17/15 : ((238+153)/63) = 17/15 : 391/63 = 17*63/15*391 = 21/5*23 = 21/115

Answer 2

It looks like you've provided an equation with mixed numbers and fractions. Let's break it down step by step:

8:10 2/3 9 5/7 : 1 23/28 1 2/15 : (3 7/9 - 2 3/7)

1. Starting with the first part: 8:10 2/3 9 5/7 This seems to be a sequence of numbers and fractions, but it's unclear what operation should be performed between them. If you could clarify the operation, I can provide a more specific answer.

2. Moving on to the second part: 1 23/28 1 2/15 Again, this appears to be a sequence of numbers and fractions, but the operation is missing. Please specify the operation you'd like to perform.

3. Finally, we have a subtraction within parentheses: (3 7/9 - 2 3/7) Let's calculate the subtraction inside the parentheses:

   3 7/9 - 2 3/7

   To subtract mixed numbers, you can convert them to improper fractions:

   (28/9) - (17/7)

   To subtract fractions with different denominators, you need a common denominator. The least common multiple (LCM) of 9 and 7 is 63. So, let's rewrite the fractions with a common denominator:

   (28/9) * (7/7) - (17/7) * (9/9) (196/63) - (153/63)

   Now, subtract the fractions:

   (196/63) - (153/63) = 43/63

   So, the result of (3 7/9 - 2 3/7) is 43/63 or simplified to 7/9.

Please provide more information or clarify the operations for the first two parts of the expression so I can help you further.
