Test: Decimals- 1

1.4 one unit and four tenths = 1 + 4 / 10
= 1 + 0.4 = 1.4.

Sixty Seven and Twenty Three One-Hundredths = 67 + 23 / 100
= 67 + 0.23 = 67.23.

Twenty Three Fiftieths

Seven Twenty Fifth

12.78 rounded to nearest tenth = 12.8.
Since the digit on hundredth place 8 > 5, the tenth place is rounded by adding 1 to 7.

3.8439 rounded to nearest hundredth = 3.84.
Since the digit on thousandth place 3 < 5, the hundredth place remains unchanged.

12.6257 to three decimal places = 12.626.
Since the digit after 5 is 7 and 7 > 5, the thousandth place is increased by 1.

106.5 rounded to nearest whole number = 107.
Since the digit after decimal is 5, the unit place is rounded by adding 1 to 6.

"2" needs to be retained in the hundreds position.
The next digit is "3" which is less than 5, so no change is needed to "2".
∴ Required answer = 2 hundreds.

12.12 ÷ 12 = 1.01
∴ Cost of each garland = 1.01.
