CBSE Class 5 Mathematics Tenths And Hundredths Worksheet Set 02

I Write the following as decimals

Question I(a). Write the following as decimals: \(\frac{6}{100}\)
Answer: \(0.06\)
In simple words: When dividing by 100, the decimal point moves two places to the left.

Exam Tip: Count the number of zeros in the denominator to know how many decimal places are needed.

Question I(b). Write the following as decimals: \(\frac{3}{1000}\)
Answer: \(0.003\)
In simple words: Dividing by 1000 requires three decimal places.

Exam Tip: Pad with zeros on the left of the numerator if necessary to match the number of zeros in the denominator.

Question I(c). Write the following as decimals: \(\frac{14}{100}\)
Answer: \(0.14\)
In simple words: 14 divided by 100 gives 14 hundredths.

Exam Tip: Ensure the decimal point is placed correctly before the tenth place digit.

Question I(d). Write the following as decimals: \(\frac{623}{1000}\)
Answer: \(0.623\)
In simple words: 623 divided by 1000 equals 623 thousandths.

Exam Tip: For denominators with three zeros, keep three digits after the decimal point.

Question I(e). Write the following as decimals: \(\frac{217}{1000}\)
Answer: \(0.217\)
In simple words: 217 divided by 1000 is written as 0.217.

Exam Tip: Check that every digit from the numerator finds its proper place after the decimal point.

Question I(f). Write the following as decimals: \(\frac{345}{100}\)
Answer: \(3.45\)
In simple words: Since the numerator is greater than the denominator, the result is greater than 1.

Exam Tip: Separate the whole number part by shifting the decimal two places from the right.

II Write the following decimals as fractions:

Question II(a). Write the following decimals as fractions: 0.25
Answer: \(\frac{25}{100}\) (or in simplest form \(\frac{1}{4}\))
In simple words: Two decimal places mean the denominator is 100.

Question II(b). Write the following decimals as fractions: 2.65
Answer: \(\frac{265}{100}\) (or \(2\frac{65}{100} = 2\frac{13}{20}\))
In simple words: Remove the decimal point and place the number over 100.

Exam Tip: Convert mixed numbers to improper fractions when an exact fraction format is needed.

Question II(c). Write the following decimals as fractions: 29.30
Answer: \(\frac{2930}{100}\) (or \(\frac{293}{10}\), or \(29\frac{3}{10}\))
In simple words: Drop the trailing zero in hundredths to simplify to tenths.

Exam Tip: Trailing zeros after the decimal point can be simplified before converting.

Question II(d). Write the following decimals as fractions: 210.145
Answer: \(\frac{210145}{1000}\) (or \(210\frac{145}{1000} = 210\frac{29}{200}\))
In simple words: Three decimal places correspond to a denominator of 1000.

Exam Tip: Ensure all digits are included in the numerator without the decimal point.

Question II(e). Write the following decimals as fractions: 125.04
Answer: \(\frac{12504}{100}\) (or \(125\frac{4}{100} = 125\frac{1}{25}\))
In simple words: Two decimal places mean the denominator is 100.

Exam Tip: Do not omit the zero in the tenths place when writing the numerator.
