Question

3 : 0,5. Заменив деление на десятичную дробь делением на натуральное число, получим: 300:5 0,3:5 3:5 30:5 3 : 0,5 = ​

Answer 1

6 тк 3:0,5=2 3/3: 1/2= 9/3*2/1=18/3=6

Answer 2

3 : 0,5 = 3 ÷ 0,5

To divide by a decimal number, we can convert it into a fraction. In this case, we convert 0,5 to a fraction by multiplying both the numerator and the denominator by 10:

0,5 * 10 = 5 10 * 10 = 10

So, 0,5 can be written as 5/10.

Now, we can rewrite the division expression:

3 : 0,5 = 3 ÷ (5/10)

To divide by a fraction, we multiply by its reciprocal:

3 ÷ (5/10) = 3 * (10/5)

Simplifying the fraction:

3 * (10/5) = 30/5

Therefore, 3 : 0,5 is equal to 30/5, which simplifies to 6.
