Processor speed is one of those tricky things that's really hard to grasp. Most retailers and computer junkies will refer to a processor's speed by the processor's clock speed (in Hertz, Hz). This is usually an indicator on how fast the processor will work. Unfortunately, that's not always true.
For example, a single-core 2.16 GHz processor will not perform near as well as a dual-core 2 GHz processor. In general, newer processors that have many cores will throw clock speed ratings out the window. (For a more accurate definition of speed, try to find out how many "flops", or calculations per second, a processor can do. This is more commonly seen on supercomputers.)
Assuming that these are both single-core processors, a clock speed of 2.16 GHz would be faster than a clock speed of 2 GHz. If either of these are multi-core, however, it's probably better to go with more cores.
Apple no longer sells a 24" iMac. The fastest 21.5" is $1,699 with a 2.8GHz Quad Core Intel Core i7 processor. The fastest 27" is $2,199 with the 3.4 GHz Quad Core Intel Core i7 processor.
Suppose 216 is 24% of X that means 100*216/X = 24 or X = 100*216/24 = 900
Apple no longer sells the 24" iMac. Your choices are a 21.5" selling for $1,299 for the 2.7 Ghz model or $1,499 for the 2.9 Ghz model. Or there is the 27" iMac 2.9 Ghz for $1,799 or the top of the line 27" with 3.2 Ghz for $1,999. The 21.5" 2.7 Ghz model will do all you want. There is no registry on a Mac and you do not need to install security software. Therefore the Mac operates just great with a slower processor than a Windows PC.
216 - 24 = 192
24
9
LCM(27, 24) = 216.
216 24*9 = 216 27*8 = 216
Since 24 is a factor of 216, it is automatically the GCF.
9 x 24 = 216
Greatest Common Divisor (GCF) for 24 216 120 is 24.
24 24 x 9 = 216
