Decimals Test-1

The product of 10.8 and 1.3 is calculated as follows:

• First, multiply the two numbers: 10.8 and 1.3 .
• The calculation yields 14.04 .
• This result can be understood as:
  • 10.8 represents the first number.
  • 1.3 is the multiplier.

Thus, the final answer is 14.04 .

The result of multiplying 80.2 by 5.04 is .

The calculation yields:

• 404.208

This means that 80.2 multiplied by 5.04 equals 404.208 .

0.005 ÷0.25 can be calculated by dividing 0.005 by 0.25. Here’s how to understand this division:

• When you divide a smaller number by a larger number, the result is usually less than 1.
• In this case, 0.005 is much smaller than 0.25.
• The actual division gives you a decimal number.

The calculation can be simplified:

• 0.005 divided by 0.25 equals 0.02.
• This means that 0.005 is 2% of 0.25.

Thus, the result of the division is 0.02 .

To solve the division:

• We need to divide 36.45 by 0.2 .
• To simplify this, we can multiply both numbers by 10 to eliminate the decimal in 0.2 .
• This changes the equation to 364.5 divided by 2 .
• Now, performing the division:
• 364.5 ÷ 2 = 182.25

The final result is 182.25 .

The result of dividing 2 by 5 is a simple mathematical calculation. Here’s how to understand it:

• The division of 2 by 5 means you are determining how many times 5 fits into 2 .
• Since 5 is larger than 2 , the result will be a decimal.
• The answer to the calculation is 0.4 .

This means that:

• 2 divided by 5 equals 0.4 , which can also be expressed as 40% .

To simplify the expression 1.07 + 2.7 ×1.02 ÷1.6, follow the order of operations (BIDMAS: Brackets, Indices, Division, Multiplication, Addition, and Subtraction).

Step 1: First, handle the multiplication and division. 2.7 ×1.02 = 2.754

Step 2: Now, divide the result by 1.6. 2.754 ÷1.6 = 1.7225

Step 3: Finally, add 1.07 to the result. 1.07 + 1.7225 = 2.7925

Rounding to two decimal places, we get 2.79.

So, the correct answer is: A: 2.79

1 kilometre (km) is equal to:

• 1000 metres (m)

• 1,000 millilitres (ml) is a unit of volume, not distance.

• 10 decametres (dam) is also a unit of distance but not commonly used.

Thus, the correct conversion is:

• 1 km = 1000 m

1 hg is equal to

• 0.1 kg (which is equivalent to 100 grams)

• 10 kg (which is ten times greater than 1 hg)

• 100 kg (which is one hundred times greater than 1 hg)

• 1000 g (this is also equal to 1 kg)

It is just simple multiplication nothing else
The word mathematics contains 11 words
According to ques each word will take exactly 0.012 second
So to print mathematics it will take 0.012 ×11 seconds that will be equal to 0.132 seconds.
Therefore option C is correct.

To convert metres to kilometres:

• 1 kilometre (km) is equal to 1,000 metres (m).
• To convert 700 metres to kilometres, divide by 1,000 :
• 700 m ÷ 1,000 = 0.7 km .

This means:

• 700 metres is equivalent to 0.7 kilometres .
