Question

1,(3) * 3,57 как умножить ??

Answer 1

Надо 1,(3) перевести в обыкновенную дробь

х=1,(3) /*10

10х=13,(3)

10х-х=13,(3)-1,(3)

9х=12

х=12/9

потом 3 57/100 умножаем на 12/9

Answer 2

To multiply the numbers 1,(3) and 3.57, we first need to understand the notation "(3)" in 1,(3). The notation "(3)" after the digit 1 indicates a recurring decimal, which means the digit 3 repeats infinitely.

To perform the multiplication, we can follow these steps:

Step 1: Convert the recurring decimal to a fraction. Let x = 1,(3). Then, 10x = 13,(3) [Move the decimal point one place to the right] Now, subtract the original equation from the equation above to eliminate the recurring part: 10x - x = 13,(3) - 1,(3) 9x = 12 [Subtracting recurring decimals eliminates them] x = 12/9 x = 4/3

Step 2: Multiply 4/3 by 3.57 To multiply fractions, multiply the numerators together and multiply the denominators together: (4/3) * 3.57 = (4 * 3.57) / 3 = 14.28 / 3 = 4.76

So, the result of 1,(3) * 3.57 is 4.76.
