Question

72*(19/24-7/12+3/6) с решением

Answer 1

1) В скобках делаем один знаменатель., для 7/12 это 2, для 3/6- 4) Получается 19/24-14/24+12/24= 17/24
2) 72*17/24. 72- это 72/1, следовательно у нас= 72/1*17/24= 3*17(так как при сокращении 72 на 24, мы получаем 3)= 51

Answer 2

1) 19/24 - 7/12 + 3/6 = (19-14+12)/24=17/24
2) 72/1*17/24=3*17=51

Answer 3

To solve the expression, follow the order of operations (PEMDAS/BODMAS):

1. Parentheses/Brackets
2. Exponents/Orders
3. Multiplication and Division (from left to right)
4. Addition and Subtraction (from left to right)

Let's solve step by step:

Step 1: Parentheses 72 * (19/24 - 7/12 + 3/6)

Step 2: Perform the operations inside the parentheses 72 * (19/24 - 7/12 + 1/2)

Step 3: Find common denominators for the fractions (the least common multiple of 24 and 12 is 24) 72 * ((19/24) - (14/24) + (12/24))

Step 4: Perform the operations inside the parentheses 72 * (17/24)

Step 5: Multiply the fractions (72 * 17) / 24

Step 6: Multiply the numbers 1224 / 24

Step 7: Perform the division 51

So, the result of the expression is 51.
