Question

Плсс срочно какую часть от 20 копеек составляют 10 копеек какую часть квадрата в 16 клеток составляют 4 клетки какую часть часа сотавляют 30 мин какую часть часа составляют 15 мин

Answer 1

Ответ:

10 копееек - $\frac{1}{2}$

4 клеточки - $\frac{1}{4}$

30 минут - $\frac{1}{2}$

15 минут - $\frac{1}{4}$

Answer 2

Calculation of Fractions:

To determine the fraction that 10 kopeks represents out of 20 kopeks, we can use the formula:

Fraction = Part / Whole

In this case, the part is 10 kopeks and the whole is 20 kopeks. Plugging these values into the formula, we get:

Fraction = 10 / 20

Simplifying the fraction, we get:

Fraction = 1/2

Therefore, 10 kopeks represents 1/2 of 20 kopeks.

Similarly, to determine the fraction that 4 cells represent out of 16 cells in a square, we can use the same formula:

Fraction = Part / Whole

In this case, the part is 4 cells and the whole is 16 cells. Plugging these values into the formula, we get:

Fraction = 4 / 16

Simplifying the fraction, we get:

Fraction = 1/4

Therefore, 4 cells represent 1/4 of the 16 cells in the square.

Moving on to the fraction of an hour represented by 30 minutes, we can use the same formula:

Fraction = Part / Whole

In this case, the part is 30 minutes and the whole is 60 minutes (since there are 60 minutes in an hour). Plugging these values into the formula, we get:

Fraction = 30 / 60

Simplifying the fraction, we get:

Fraction = 1/2

Therefore, 30 minutes represent 1/2 of an hour.

Finally, to determine the fraction of an hour represented by 15 minutes, we can use the same formula:

Fraction = Part / Whole

In this case, the part is 15 minutes and the whole is 60 minutes (since there are 60 minutes in an hour). Plugging these values into the formula, we get:

Fraction = 15 / 60

Simplifying the fraction, we get:

Fraction = 1/4

Therefore, 15 minutes represent 1/4 of an hour.

Please note that the fractions mentioned above are simplified fractions and represent the proportion of the given parts to the whole.
