Olympiad Test: Decimals And Fractions - 2 - Class 5 MCQ

Option B accurately represents 9,842 as "Nine thousand, eight hundred, forty-two," which matches the given number exactly.

A decimal is a fractional number and is indicated by digits after a period which is called a decimal point.

Tenths have one digit after the decimal point. The decimal 0.8 is pronounced as eight tenths.

Hundredths have two digits after the decimal point. The decimal 0.06 is pronounced as six hundredths.

Thousandths follow a similar pattern. They have three digits after the decimal point. The decimal 0.005 is pronounced as five thousandths.

5/100,000 = 0.00005

Hence, five hundred-thousandths is 0.00005.

The arrangement in increasing order of given numbers 0.6 <  0.52 < 0.4981 < 0.4891 

0.4891 is the smallest among given numbers.

The hundredths digit is the second digit to the right of the decimal point, which is the 1: 356.812

The tenths place comes immediately after the decimal point and the hundredths place comes after that. In this case the digit in the tenths place is 7 and the digit in the hundredths place is 2

231/1000 is shown in place value chart below.

the following choices lists these decimals in order from least to greatest is 0.091, 0.9, 0.910

Sum = 3.6 + 0.75 = 4.35
Now, 
4.35 ÷ 5 = 0.87

The smallest digit in this number is 2, and it is in the thousandths place (option 3).

• The digit 4 is in the hundreds place.
• The digit 9 is in the tens place.
• The digit 8 is in the units (ones) place.
• The digit 6 is in the tenths place.
• The digit 3 is in the hundredths place.
• The digit 2 is in the thousandths place.
• The digit 7 is in the ten-thousandths place.

To round the number 2.0847 to two decimal places, you look at the third decimal place to determine whether to round up or down.

Here’s the process:

• The number is 2.0847.
• The second decimal place is 8.
• The third decimal place is 4.

Since the third decimal place (4) is less than 5, you do not round up the second decimal place.

So, 2.0847 rounded to two decimal places is:

2.08

9 is the third digit to the right of the decimal point, so it is 9 thousandths.(2 is in the tenths place, 4 is in the hundredths place, 9 is in the thousandths place and 5 is in the ten-thousandths place)

The tenths digit is the first digit to the right of the decimal point, which is the 7.

To add 2.372 to 14.04, align the decimal points and add the numbers: 2.372 +14.040 ------- 16.412.

6 is the first digit to the right of the decimal point, so it is 6 tenths.

The highest place value in the number is the thousands, but that’s not what the question is asking. The largest digit in the number is 9, which is in the tenths place.

The lowest place value in the number is the ten-thousandths, but that’s not what the question is asking. The smallest digit in the number is 2, which is in the thousandths place: 489.6327
