4th Grade Tenths, Hundredths and Decimal Notation Quiz: 10 Questions with Explanations

A 0.03B 3.10C 0.3D 0.13

3 tenths is 0.3. The hundredths place is the second digit, so 0.03 is 3 hundredths.

A \(\frac{7}{100}\)B \(\frac{17}{100}\)C \(\frac{70}{100}\)D \(\frac{70}{10}\)

Multiply the top and bottom by 10 to get \(\frac{70}{100}\).

A 4.5B 0.045C 0.54D 0.45

45 of 100 squares are shaded, so 45 hundredths = 0.45.

A 0.34B 0.7C 0.43D 3.4

\(\frac{3}{10}\) = \(\frac{30}{100}\), and \(\frac{30}{100}\) + \(\frac{4}{100}\) = \(\frac{34}{100}\) = 0.34. Adding 3 + 4 = 7 forgets the place values.

A 0.5B 0.45C 0.38D 0.09

0.5 = 0.50, which is greater than 0.45. A longer decimal is not always greater.

A 0.63B 0.36C 0.6D 3.6

P is 6 small marks after 0.3, so it is 0.36.

A \(0.4 > 0.38\)B \(0.4 < 0.38\)C \(0.4 = 0.38\)D \(0.38 > 0.4\)

0.4 = 0.40, which is greater than 0.38.

A 8 tenthsB 8 hundredthsC 8 onesD 80 tenths

The second digit after the decimal point is the hundredths place.

A $3.04B $0.34C $0.07D $0.70

3 dimes = 30 cents and 4 pennies = 4 cents, so 34 cents = $0.34.

A Liam, because 19 is greater than 2B They jumped the same distanceC Liam, because 4.19 has more digitsD Mei, because 4.20 is greater than 4.19

Write 4.2 as 4.20. Then 20 hundredths is greater than 19 hundredths.
