Question

5/13:3+2/39*2=? (67/10-17/10):5=? помогите пожалуйста помогите

Answer 1

(67/10 - 17/10) : 5 = 50/10 : 5 = 1            50/10 сокращаем на 10, будет 5/1 или 5 целых, а 5 : 5 будет 1

Answer 2

(67/10 - 17/10) : 5 = 50/10 : 5 = 1            50/10 сокращаем на 10, будет 5/1 или 5 целых, а 5 : 5 будет 1

Answer 3

To solve the equation 5/13:3 + 2/39*2, we need to follow the order of operations, which is commonly known as PEMDAS (Parentheses, Exponents, Multiplication and Division, and Addition and Subtraction).

Let's break down the equation step by step:

1. 5/13:3: To divide 5/13 by 3, we need to multiply 5/13 by the reciprocal of 3, which is 1/3. So, 5/13 divided by 3 is equal to (5/13) * (1/3). Multiplying the numerators (5 * 1) gives us 5, and multiplying the denominators (13 * 3) gives us 39. Therefore, 5/13 divided by 3 is equal to 5/39.

2. 2/39*2: To multiply 2/39 by 2, we multiply the numerators (2 * 2) to get 4 and multiply the denominators (39 * 1) to get 39. Therefore, 2/39 multiplied by 2 is equal to 4/39.

Now, let's add the results of the two calculations:

3. 5/39 + 4/39: To add 5/39 and 4/39, we add the numerators (5 + 4) to get 9 and keep the common denominator of 39. Therefore, 5/39 + 4/39 is equal to 9/39.

Simplifying the fraction 9/39, we can divide both the numerator and denominator by their greatest common divisor, which is 3. Dividing 9 by 3 gives us 3, and dividing 39 by 3 gives us 13. Therefore, 9/39 simplifies to 3/13.

So, the solution to the equation 5/13:3 + 2/39*2 is 3/13.

Now, let's move on to the next part of your question.

To solve the equation (67/10 - 17/10):5, we again need to follow the order of operations.

1. 67/10 - 17/10: To subtract 17/10 from 67/10, we subtract the numerators (67 - 17) to get 50 and keep the common denominator of 10. Therefore, 67/10 - 17/10 is equal to 50/10.

2. 50/10:5: To divide 50/10 by 5, we divide the numerator (50) by the denominator (10 * 5), which gives us 50/50. Simplifying this fraction, we can divide both the numerator and denominator by their greatest common divisor, which is 10. Dividing 50 by 10 gives us 5, and dividing 50 by 10 also gives us 5. Therefore, 50/10 simplifies to 5/1, which is equal to 5.

So, the solution to the equation (67/10 - 17/10):5 is 5.
