А)2 1/6*3, б) (5/12+1 1/3)*3 ПЖ СРОЧНО ПОМОГИТЕ ДАЮ 40 БАЛЛОВ!!!!!!!!!​

Answer 1

а) 2 целых 1/6 = 13/6 · 3 = 13/2 = 6 целых 1/2;

б) (5/12 + 1 1/3) · 3 = 5 1/4

1) 5/12 + 1 1/3 = 5/12 + 4/3 = 5/12 + 16/12 = 21/12

2) 21/12 · 3 = 21/4 = 5 целых 1/4.

Answer 2

Ответ:

(2+1/6)*3=6+1/2

(5/12+1+1/3)*3=5+1/4

Пошаговое объяснение:

(2+1/6)*3=6+1/2

(5/12+1+1/3)*3=(5/12+1+4/12)*3=(1+9/12)*3=(1+3/4)*3=7/4*3=5+1/4

Answer 3

Calculation: 2 + 1/6 * 3

To calculate the expression 2 + 1/6 * 3, we need to follow the order of operations, which is commonly known as PEMDAS (Parentheses, Exponents, Multiplication and Division, and Addition and Subtraction).

First, let's simplify the multiplication: 1/6 * 3 = 1/2.

Now, we can rewrite the expression as 2 + 1/2.

To add fractions, we need to have a common denominator. In this case, the common denominator is 2.

Converting 2 to a fraction with a denominator of 2, we get 4/2.

Now, we can add the fractions: 4/2 + 1/2 = 5/2.

Therefore, the result of the expression 2 + 1/6 * 3 is 5/2.

Calculation: (5/12 + 1 + 1/3) * 3

To calculate the expression (5/12 + 1 + 1/3) * 3, we again need to follow the order of operations.

First, let's simplify the addition: 5/12 + 1 + 1/3.

To add fractions, we need to have a common denominator. In this case, the common denominator is 12.

Converting 1 to a fraction with a denominator of 12, we get 12/12.

Now, we can add the fractions: 5/12 + 12/12 + 1/3.

Combining the numerators, we get 5 + 12 + 4 = 21.

The denominator remains the same: 12.

So, the expression simplifies to 21/12.

Now, let's multiply the result by 3: (21/12) * 3.

To multiply fractions, we simply multiply the numerators and denominators.

Multiplying 21 by 3 gives us 63, and multiplying 12 by 1 gives us 12.

Therefore, the result of the expression (5/12 + 1 + 1/3) * 3 is 63/12, which can be further simplified to 21/4.

I hope this helps! Let me know if you have any further questions.
