Question

Число уменьшили в 1,6 раза. На сколько процентов уменьшили число? Нужно с объяснением.

Answer 1

уменьшить в 1.6 раз это то же самое,что умножить на 10/16=0.625

то есть уменьшают на 37,5 процентов.

так как все это сто процентов при умножении на 0.625 мы получается уменьшаем на 1-0.625=0.375*100=37.5

ответ 37.5 процентов.

Answer 2

Calculating Percentage Decrease

To calculate the percentage decrease when a number is reduced by a certain factor, we can use the formula:

Percentage Decrease = ((Initial Number - Final Number) / Initial Number) * 100

In this case, the number was reduced by 1.6 times, which means the final number is 1.6 times smaller than the initial number.

Calculation

Let's assume the initial number is X. The final number after reducing it by 1.6 times will be X / 1.6.

Using the formula for percentage decrease:

Percentage Decrease = ((X - X / 1.6) / X) * 100

Now, let's calculate the percentage decrease using this formula.

Result

The percentage decrease when a number is reduced by 1.6 times is approximately 37.5%.

This calculation is based on the formula for percentage decrease and the given reduction factor of 1.6 times.
