Scissors[ edit ] For example right-handed scissors are arranged so that, in the right hand, fingers and thumb push the blades together laterally, creating the shearing action essential to scissors' utility. In the left hand, however, fingers and thumb tend to force right-handed blades apart, so that, rather than being sheared, the work-material is merely hacked, as by a knife, or slips between the blades uncut.
Dividing fractions Video transcript Divide. Simplify the answer and write as a mixed number. So the first thing we want to do since both of these are mixed numbers is to convert them both into improper fractions.
Or another way to come up with this 9, you take 4 times 2, which is 8, plus 1.
That gives you 9. You're going to have 4 in the denominator, and then the numerator is going to be 4 times 1, which is 4, plus 3, which is 7. So this is the exact same problem here. And we saw in several videos already that dividing by a fraction is the same thing as multiplying by its reciprocal.
So this is equivalent to-- so these are all equivalent. Now, we could just multiply these. We could just say this is 9 times 4, which would be 36, over 4 times 7, which is 28, and then try to put it in lowest terms, or we could do it right now because it would be simpler.
We have a 4 in the numerator.
We have a 4 in the denominator, that'll eventually be in the denominator, so let's divide our eventual numerators and our eventual denominators both by 4.
So you divide this 4 by 4, you get 1. This 4 by 4, you get 1. So now when you multiply it, you get 9 times 1, which is 9, over 1 times 7, which is 7. So we have our answer, but right now, it's an improper fraction.
They want us to write it as a mixed number.
And to figure it out as a mixed number, we can do it in our heads now. I think we've seen this enough times.
We say how many times does 7 go into 9? Well, it goes into it exactly one time, but when you take 7 into 9 one time, what do you have left over? Well, you're going to have 2 left over, right?
You need 2 more to get to 9.I'd like to write log to 2 different log files from the same process.
