A \(6+0.04\)B \(6+0.4\)C \(6+0.004\)D \(60+0.4\)

The 4 is in the hundredths place, so it is worth 0.04.

A 0.79B 0.8C 0.081D 0.78

Write them with three places: 0.800, 0.790, 0.081, 0.780. The greatest is 0.800.

A 2.30 is greaterB 2.30 is lessC They are equalD You cannot tell

A zero at the end of a decimal does not change its value, so 2.30 = 2.3.

A 5.6B 5.7C 5.65D 6

The hundredths digit is 4, which is less than 5, so round down to 5.6.

A 0.99B 1.00C 0.90D 1.10

The thousandths digit is 5, so round the 9 up. The carry makes 1.00.

A 0.4B 0.004C 0.04D 4

The 4 is in the hundredths place, so its value is 0.04.

A 0.9, 0.49, 0.409, 0.049B 0.409, 0.049, 0.49, 0.9C 0.049, 0.49, 0.409, 0.9D 0.049, 0.409, 0.49, 0.9
