Question

(7:5\6-73\9)*12\5-((3\8+5\6+5\12)*8\25)=

Answer 1

(42/5-73/9)*12/5-(13*1/25);
13/45*12/5-13/25- умножили 13 и 1/25;
Сокращаем 45 и 12 на 3;
Умножаем дроби:13/15*4/5-13/25;
Далее нам надо вычитать дроби: 52/75-13/25=13/75
Так, вроде)

Answer 2

To solve this expression, we can use the order of operations, also known as PEMDAS (parentheses, exponents, multiplication and division, addition and subtraction).

1. Simplify the fractions within the expression:

• 7:5/6 = 7/5 * 6/1 = 42/5
• 73/9 = 8 1/9
• 3/8 + 5/6 + 5/12 = 9/8

2. Substitute the fractions with their simplified values into the expression:

(42/5 - 8 1/9) * 12/5 - ((9/8) * 8/25)

3. Convert the mixed number to an improper fraction:

8 1/9 = (9 * 8 + 1) / 9 = 73/9

4. Simplify the expression further:

(42/5 - 73/9) * 12/5 - (9/8 * 8/25) = ((378/45) - (325/45)) * 12/5 - (9/8 * 8/25) = (53/45) * 12/5 - (9/8) * (2/25) = (212/45) - (9/100) = 4231/900

Therefore, the value of the expression is 4231/900.
