We can do from 11 which one doesn't belong okay so we have three expressions here first one is five times one over 10 plus one times one over 100 plus four times one over 1 ,000 let's actually calculate this body first this one becomes 0 .5 this one becomes 0 .01 and this one becomes 0 .004 so summing these are we obtain 0 .514 so this matches with the expression the right -hand expression 0 .514 and the last one is 5 and 14th or excuse me the third one is 5 and 14th so this means 5 .14 and the other one we have 1st 0 .10, 500s, 1, and thousands, 4.
01:18
So, the obvious one that is, doesn't belong, is this one, 5 and 14 ,100th, because it evaluates to 5 .14.
01:28
Okay, we can do 12.
01:31
Okay, so we have a 0 .732, and this one is what we're referring to.
01:39
And okay so we can evaluate from a two times one over 1000 this this means that 0 .123 this means that one two would be three digits after the after the decimal points so 0 .02 which is correct because this one is 0 .002.
02:24
So a is we're gonna check this one and b 2000 so 2000 definitely do not is equal to 0 .002 so we're not gonna check this one c...
