Decimals Test-2

The value of 1.1 x 0.1 can be calculated as follows:

• The multiplication of 1.1 and 0.1 results in 0.11 .
• This is because:
  • 1.1 can be understood as 1.1 times 1 .
  • When you multiply by 0.1 , you are effectively shifting the decimal point one place to the left.
• Therefore, the answer is 0.11 .

1 rupee (Rs. 1) is equal to 100 paise.

So, to convert Rs. 0.08 to paise:

0.08 ×100 = 8 paise

The correct answer is: B: 8 paise

To convert 3 kg and 50 gm into kilograms:

• First, convert grams to kilograms. Since 1 kg is equal to 1000 gm , you can convert:
• 50 gm is equal to 0.050 kg .
• Next, add this to 3 kg :
• 3 kg + 0.050 kg = 3.050 kg .

Therefore, the final answer is 3.050 kg .

6 divided by 0.3 equals:

• The calculation can be thought of as finding out how many times 0.3 fits into 6 .
• To simplify:
  • Convert 0.3 to a fraction: 0.3 = 3/10 .
  • Dividing by a fraction can be done by multiplying by its reciprocal:
  • So, 6 ÷0.3 = 6 ×(10/3) .
  • This simplifies to 60 ÷3 = 20 .

Thus, 6 divided by 0.3 equals 20 .

The calculation involves dividing two numbers:

213 divided by 2.13 equals 100 .

• First, convert both numbers into the same format for easier division.
• The operation can be simplified as follows:
  • 0.213 can be expressed as 213.
  • 0.00213 can be expressed as 2.13.
• Now, perform the division:

This means that: The correct answer is 100 .

To solve the expression 1 divided by 0.04, we can follow these simple steps:

• First, we can rewrite 0.04 as a fraction: 0.04 = 4/100 .
• This can be simplified to 1/25 .
• Now, substituting this back into our expression:
• 1 / 0.04 becomes 1 / (4/100) .
• When dividing by a fraction, we multiply by its reciprocal:
• This means we calculate 1 * (100/4) .
• This simplifies to 100/4 = 25 .

The final answer is 25 .

Understanding Decimal Values:

• Decimal numbers can represent values less than one.
• For example:
• 0.0009 is a small value, significantly less than one.
• 0.09 is equivalent to nine hundredths, or 9%.
• 0.9 represents nine tenths, which is very close to one.
• 9 is a whole number and much larger than the others.

To clarify:

• When comparing these values, notice their size relative to one.
• Each decimal point shifts the value, making it smaller or larger.

Thus, the largest number in this set is 0.9 .

To find the value of ? in the equation .04 x ? = .000016:

• Start with the equation: .04 x ? = .000016 .
• To isolate ?, divide both sides by 0.04 :
• Calculation: ?. = .000016 / .04 .
• Perform the division: ?. = 0.0004 .

The value of ? is 0.0004 .

o solve the equation , we will use cross-multiplication.

1. Set up the equation :

2. Cross-multiply :
144 ⋅x = 14.4 ⋅0.144

3. Calculate  14.4 ⋅0.144 :
- First, we can multiply:
14.4 ⋅0.144 = 2.0736

4. Now, substitute back into the equation :
144 x = 2.0736

5. Solve for  x :
- Divide both sides by 144:
x=2.0736 / 144

6. Calculate the division :
x = 0.0144

Final Answer:
The value of  x  is  0.0144.
