Fractions and Decimals Test - 2

As we know, numbers left of the decimal place are seen as ones, tens, hundred, thousand and so on whereas numbers right of the decimal place are seen as a single unit,

Hence, 16.09 will be called Sixteen-point-zero-nine.

0.6

We can write it as

= 6/10

= 3/5

6985.253

Counting from right, there are three decimal places before the decimal sign.

0.6

We can write it as

= 6/10

Here the HCF of 6 and 10 is 2

= (6 ÷ 2)/ (10 ÷ 2)

So we get

= 3/5

3.45

We can write it as

= 345/ 100

Here the HCF of 375 and 100 is 25

= (345 ÷ 5)/ (100 ÷ 5)

So we get

= 69/20

0.000090

Counting from right, there are six decimal places before the decimal sign.

0.9873

Counting from right, there are four decimal places before the decimal sign.

5.710

Counting from right, there are three decimal places before the decimal sign.

4.025

We can write it as

= 4025/1000

Here the HCF of 4025 and 1000 is 25

= (4025 ÷ 25)/ (1000 ÷ 25)

So we get

= 161/ 40

1.2

We can write it as

= 12/10

Here the HCF of 12 and 10 is 2

= (12 ÷ 2)/ (10 ÷ 2)

So we get

= 6/5

3/4

By division we get

= 0.75

67/10,000

We can write it as

= 67/10,000

= 0.0067

Counting from right, there are five decimal places before the decimal sign.

99.4

Counting from right, there is one decimal places before the decimal sign.

As we know, numbers left of the decimal place are seen as ones, tens, hundred, thousand and so on whereas numbers right of the decimal place are seen as a single unit,

Hence, 610.214 will be called six hundred ten-point-two-one-four

0.75

We can write it as

= 75/100

Here the HCF of 75 and 100 is 25

= 75 ÷ 25)/ (100 ÷ 25)

So we get

= 3/4

39/100

We can write it as

=39/100

= 0.39

6379/10⁴

We can write it as

= 6379/10000

= 0.6379

0.80

We can write it as

= 80/100

Here the HCF of 80 and 100 is 20

=(80/  )/ (100/) 

So we get

= 4/5

As we know, numbers right of the decimal place are seen as a single unit.

Hence, 0.0036 will be called zero-point-zero-zero-three-six.
