Write 12.54 as 12.54/1. Multiply both numerator and denominator by 10 for every number after the decimal point
<span>12.54 × 100/1 × 100</span><span> = </span><span>1254/100. </span>Reducing the fraction gives
<span>627/<span>50. Idk if this is actually right, but here you go. </span></span>
You can compare and contrast whole number, integers, and rational numbers. For instance, some are negative some aren't!
To find the area of the circle with diameter = 18 cm
We will use the formula:

where r= radius of the circle
From the quesion diameter = 18 cm
radius = diameter/2
radius = 18cm/2 = 9 cm
substituting r = 9cm into the formula


The above answer is when we are to leave the answer in terms of π
Otherwise if π is given to be 3.14 or 22/7 , we will simply substitute into the formula
That is given that π= 3.14
500 what?
