\( 0.75+0.35= \)
Determine the number of ones in the following number:
0.81
Determine the number of hundredths in the following number:
0.96
Determine the number of ones in the following number:
0.73
Determine the number of ones in the following number:
0.07
To solve this problem, we will add the decimal numbers 0.75 and 0.35 by aligning them according to their decimal points:
Step 1: Align the numbers vertically by their decimal points:
Step 2: Add the digits starting from the rightmost column (hundredths place):
- Hundredths place: . Write 0 and carry over 1 to the tenths place.
- Tenths place: . Write 1 and carry over 1 to the units place.
- Units place: .
Step 3: Write the final sum by placing the decimal point correctly below the decimal points of the addends:
The sum of 0.75 and 0.35 is therefore , which can be simplified to by removing the trailing zero after the decimal point.
The correct answer is, therefore, , corresponding to choice .

Determine the number of ones in the following number:
0.81
To solve this problem, we need to examine the decimal number and count the number of '1's present:
Now, count the number of '1's in :
There is only one '1' in the entire number because it appears only once after the decimal point.
Thus, the total number of ones in is 0, since the task is to count ones in the whole number, and there are no ones in the integer part of , nor in the remaining digits .
Therefore, the solution to the problem is , which corresponds to choice 3.
0
Determine the number of hundredths in the following number:
0.96
To solve this problem, we'll follow these steps:
Now, let's work through each step:
Step 1: Consider the decimal number . In decimal representation, the digit immediately after the decimal point represents tenths, and the digit following that represents hundredths.
Step 2: In the number , the digit is in the tenths place, and the digit is in the hundredths place.
Step 3: Therefore, the number of hundredths in is .
Thus, the solution to the problem is that there are 6 hundredths in the number .

Determine the number of ones in the following number:
0.73
To solve this problem, let's carefully examine the decimal number digit by digit:
We observe that there are no digits in the sequence of that are the number '1'. Therefore, there are no '1's in the decimal number .
Thus, the number of ones in the number is 0.
The correct choice, given the options, is choice id 1: 0.
0
Determine the number of ones in the following number:
0.07
To solve this problem, we'll examine the given decimal number, , to identify how many '1's it contains.
Let's break down the number :
None of the digits in the number are equal to '1'.
Therefore, the number of ones in is 0.
0
Determine the number of ones in the following number:
0.4
Determine the number of tenths in the following number:
1.3
Write the following decimal as a fraction and simplify:
\( 0.75 \)
Write the following decimal fraction as a simple fraction and simplify:
\( 0.36= \)
Write the following decimal fraction as a simple fraction and simplify:
\( 0.58 \)
Determine the number of ones in the following number:
0.4
To solve this problem, we'll follow these steps:
Now, let's work through each step:
Step 1: The number given is 0.4. This number is composed of the digits '0', '.', and '4'.
Step 2: Identify any '1's among these digits. There are no '1's in this sequence of digits.
Step 3: Thus, the count of the digit '1' in the number 0.4 is zero.
Therefore, the number of ones in the number 0.4 is .
0
Determine the number of tenths in the following number:
1.3
To solve this problem, we'll follow these steps:
Now, let's work through each step:
Step 1: The problem asks us to count the number of tenths in the decimal number 1.3. This involves understanding the place value of each digit.
Step 2: In the decimal 1.3, the digit '1' represents the whole number and does not contribute to the count of tenths. The digit '3' is in the tenths place.
Step 3: Since the digit '3' is in the tenths place, it denotes 3 tenths or the fraction .
Therefore, the number of tenths in 1.3 is .
