Express 8/25 as a decimal

Detailed Solution for Olympiad Test: Decimals And Fractions - 3 - Question 8

Divide 8 by 25 : 8÷25=0.32
OR
Make the bottom number some multiple of 10:
We can multiply 25 by 4 to make 100
So multiply top and bottom by 4. You will get 32/100.
Now, Write that fraction as a decimal: Write down 32 with the decimal point 2 spaces from the right (because 100 has 2 zeros): 0.32

Olympiad Test: Decimals And Fractions - 3 - Question 11

Express 4/9 as a decimal correct to 3 decimal places.

Detailed Solution for Olympiad Test: Decimals And Fractions - 3 - Question 11

Step 1 : There is no way to multiply 9 to become 10 or 100 or any “1 followed by 0s”, but we can calculate an approximate decimal by choosing to multiply by 111.
Step 2 : Multiply top and bottom by 111:
Step 3 : Now, 999 is nearly 1,000, so let us write down 444 with the decimal point 3 spaces from the right (because 1,000 has 3 zeros): 0.444 correct to 3 decimal places.

Olympiad Test: Decimals And Fractions - 3 - Question 17

Which of the following is a larger fraction?

Olympiad Test: Decimals And Fractions - 3 - Question 18

Which one of the following fractions is the largest?

Detailed Solution for Olympiad Test: Decimals And Fractions - 3 - Question 18

To compare the fractions, we need to write each of them as an equivalent fraction with a common denominator i.e. we must find the least common multiple of 36, 9, 6 and 4.
Since 9, 6 and 4 are all factors of 36, the least common multiple is 36 So change them all to equivalent fractions with denominator 36:
7/9 will become 28/36
5/6 will become 30/36
3/4 will become 27/36
Now they all have the same denominator, we just need to find the one with the largest numerator, which is 30. Therefore, 5/6 is the largest fraction.
