Multiply and divide mixed numbers
In the previous section, you learned how to multiply and divide fractions. All of the examples there used either proper or improper fractions. What happens when you are asked to multiply or divide mixed numbers? Remember that we can convert a
mixed number to an
improper fraction . And you learned how to do that in
Visualize Fractions .
Notice that we left the answer as an improper fraction,
$\frac{25}{12},$ and did not convert it to a mixed number. In algebra, it is preferable to write answers as improper fractions instead of mixed numbers. This avoids any possible confusion between
$2\frac{1}{12}$ and
$2\xb7\frac{1}{12}.$
The words
quotient and
ratio are often used to describe fractions. In
Subtract Whole Numbers , we defined quotient as the result of division. The quotient of
$a\phantom{\rule{0.2em}{0ex}}\text{and}\phantom{\rule{0.2em}{0ex}}b$ is the result you get from dividing
$a\phantom{\rule{0.2em}{0ex}}\text{by}\phantom{\rule{0.2em}{0ex}}b\phantom{\rule{0.2em}{0ex}},$ or
$\frac{a}{b}.$ Let’s practice translating some phrases into algebraic expressions using these terms.
can you tell how can i economics honurs(BSC) in reputed college?
Soumya
through hard study and performing well than expected from you
Mitiku
what should i prepare for it?
Soumya
prepare first, in psychologically as well as potentially to sacrifice what's expected from you, when I say this I mean that you have to be ready, for every thing and to accept failure as a good and you need to change them to potential for achievement of ur goals

Jeannette has $5 and $10 bills in her wallet. The number of fives is three more than six times the number of tens. Let t represent the number of tens. Write an expression for the number of fives.
why surface tension is zero at critical temperature
Shanjida
I think if critical temperature denote high temperature then a liquid stats boils that time the water stats to evaporate so some moles of h2o to up and due to high temp the bonding break they have low density so it can be a reason
