5)4810:37=130

Answer 2

Решение примеров:

1) 1,2 : 0,48

To divide decimal numbers, we can follow these steps: 1. Move the decimal point in the divisor (0,48) to the right until it becomes a whole number. In this case, we move the decimal point two places to the right, resulting in 48. 2. Move the decimal point in the dividend (1,2) the same number of places to the right as in step 1. In this case, we move the decimal point two places to the right, resulting in 120. 3. Perform the division of the modified dividend (120) by the modified divisor (48). 120 ÷ 48 = 2.5

Therefore, the solution to the first example is 2.5.

2) 0,806 : 31

Following the same steps as above: 1. Move the decimal point in the divisor (31) to the right until it becomes a whole number. No movement is needed in this case since 31 is already a whole number. 2. Move the decimal point in the dividend (0,806) the same number of places to the right as in step 1. In this case, no movement is needed since 0,806 already has the same number of decimal places as the divisor. 3. Perform the division of the modified dividend (0,806) by the modified divisor (31). 0,806 ÷ 31 ≈ 0,026

Therefore, the solution to the second example is approximately 0,026.

3) 5 : 2,5

Here, both the dividend and divisor are already whole numbers. So we can directly perform the division. 5 ÷ 2,5 = 2

Therefore, the solution to the third example is 2.

4) 7,44 : 0,4

Following the same steps as above: 1. Move the decimal point in the divisor (0,4) to the right until it becomes a whole number. In this case, we move the decimal point one place to the right, resulting in 4. 2. Move the decimal point in the dividend (7,44) the same number of places to the right as in step 1. In this case, we move the decimal point one place to the right, resulting in 74,4. 3. Perform the division of the modified dividend (74,4) by the modified divisor (4). 74,4 ÷ 4 = 18,6

Therefore, the solution to the fourth example is 18,6.

5) 48,1 : 0,37

Following the same steps as above: 1. Move the decimal point in the divisor (0,37) to the right until it becomes a whole number. In this case, we move the decimal point two places to the right, resulting in 37. 2. Move the decimal point in the dividend (48,1) the same number of places to the right as in step 1. In this case, we move the decimal point two places to the right, resulting in 4810. 3. Perform the division of the modified dividend (4810) by the modified divisor (37). 4810 ÷ 37 ≈ 130

Therefore, the solution to the fifth example is approximately 130.

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