Пошаговое объяснение:

1% / 100% = 0,01

Answer 2

1) 1% is equal to 0.01, not 0.1. So, the correct option is 2) 0.01.

To understand this, let's break it down: - 1% means 1 out of 100 parts. - In decimal form, we represent 1% as a fraction with the denominator 100, which is 1/100. - To convert this fraction to a decimal, we divide the numerator (1) by the denominator (100), which gives us 0.01. - Therefore, 1% is equal to 0.01 as a decimal.

2) To write 1152° as a decimal fraction, we need to determine the place value of the digit 2 in the number 1152.

The digit 2 is in the "ones" place, so its place value is 1.

To convert 1152° to a decimal fraction, we divide it by 10 raised to the power of its place value.

In this case, we divide 1152 by 10^1 (which is 10), and we get 115.2.

Therefore, 1152° can be written as the decimal fraction 115.2.
