Question

In the English test, Shelly scored three times as many marks as John. If Shelly scored a total of 97.2. What is John's score in the test?

• A. 32.4
• B. 3.24
• C. 324
• D. 291.6

Answer 1

The correct option is A 32.4

$\text{Shelly's score}=3\times \text{John's score}$
$97.2=3\times \text{John's score}$
$\text{John's score}=97.2÷3$

Steps to solve $97.2÷3$

Step 1: Count the number of digits after a decimal point

Step 2: Ignore a decimal point and perform the long division, as you would with whole numbers as follows

Step 3: Now place a decimal point back.
97.2 has 1 decimal places. So, place the decimal point 1 place to the left in the quotient 324.

Hence, John's score in the test was 32.4
