You just multiply like that.. and reduce it if possible. Got it?

4. phi Group Title

kymber told you the rule: multiply top times top and bottom times bottom

But you can do "canceling" which makes the problem easier notice that $\frac{10}{21} \cdot \frac{3}{5} = \frac{10\cdot 3}{21 \cdot 5}$ but you know (right?) that 10 * 3 is the same as 3*10, so you could write this as $\frac{3\cdot 10}{21 \cdot 5} = \frac{3}{21} \cdot \frac{10}{5}$ you can divide top and bottom by 3 to simplify 3/21 to 1/7 and simplify 10/5= 2 so the problem is $\frac{1}{7}\cdot \frac{2}{1} = \frac{2}{7}$

Thank You Alot Hes Asking For Canceling So Yep I Got It Right Thanks

$\frac{ 3 }{ 4}\times \frac{ 7 }{ 9 }$

but 3/9 is 1/3 so 3/4 x 7/9 is the same as 3/9 x 7/4 = 1/3 x 7/4
