Answer:
<u><em>C. To square a number, multiply the number by itself.</em></u>
If p=40; q=40 and r=100, p+q+r=180
2(10.8) = 21.6
2(8.3) = 16.6
21.6 + 16.6
Answer: 38.2
If Fraction has denominators such as 10, 100 or 1000 it would be easy to convert it into decimal. Like this:
6
------- - Fraction.
100
Now, Write down the number six and add zeros to it. If the denominator has 2 zeros in it then the there should be two decimal numbers. Answer for the above fraction would be: 0.06.
If a fraction does not have denominators such as 10, 100 or 1000, then do the following:
6
------
25
The above fraction's denominator is not 10, 100 or 100. So, multiply the numerator and the denominator with a number that would give you the denominator as 10, 100 or 1000.
6 × 4 = 24
----- ---- -------
25 × 4 = 100
Now, you can convert it as 0.24
If a fraction has a denominator that cannot be converted into 10, 100 or 1000, then directly divide and write the decimal.
