Question

2,4 • 1 5/12•1 7/17-3 1/7 : 1 4/7=

Answer 1

Ответ:

2 4/5 или 2,8

Пошаговое объяснение:

2,4 * 1 5/12 * 1 7/17 - 3 1/7 : 1 4/7 = 24/10 * 17/12 * 24/17 - 22/7 : 11/7 =

(24*17*24)/(10*12*17) - 22/7 * 7/11 = 24/5 - 2 = 4 4/5 - 2 = 2 4/5 = 2,8

Answer 2

Answer 3

To solve this expression, we need to follow the order of operations (also known as PEMDAS/BODMAS) which stands for Parentheses/Brackets, Orders/Exponents, Division/Multiplication, and Addition/Subtraction.

Let's break down the expression step by step:

Step 1: Simplify the division operation: 3 1/7 ÷ 1 4/7

To divide fractions, we need to multiply the first fraction by the reciprocal of the second fraction. The reciprocal of 1 4/7 is 7/4.

3 1/7 ÷ 1 4/7 = (22/7) ÷ (7/4)

To divide fractions, we multiply the numerator of the first fraction by the reciprocal of the second fraction:

= (22/7) * (4/7) = (22 * 4) / (7 * 7) = 88/49

So, 3 1/7 ÷ 1 4/7 simplifies to 88/49.

Step 2: Simplify the multiplication operation: 2,4 • 1 5/12 • 1 7/17

We can convert the mixed numbers to improper fractions:

2,4 = 2 + 4/10 = 2 + 2/5 = 12/5 1 5/12 = (1 * 12 + 5) / 12 = 17/12 1 7/17 = (1 * 17 + 7) / 17 = 24/17

Now we multiply these fractions:

(12/5) • (17/12) • (24/17)

We can cancel out some common factors:

(12/5) • (24/12) = (2 * 2) / 5 = 4/5

So, 2,4 • 1 5/12 • 1 7/17 simplifies to 4/5.

Step 3: Perform the final division: 4/5 ÷ 88/49

To divide fractions, we multiply the first fraction by the reciprocal of the second fraction:

(4/5) ÷ (88/49) = (4/5) * (49/88)

Now we multiply the numerators and denominators:

= (4 * 49) / (5 * 88) = 196/440 = 49/110

Therefore, 2,4 • 1 5/12 • 1 7/17 - 3 1/7 ÷ 1 4/7 simplifies to 49/110.
