please help with both questions. I have test today and I need to review

3.
first, we have to express the mixed number as a simple fraction :
3 1/4
For the numerator (top number) we have to multiply the whole number (3) by the denominator ( bottom number =4) and add the numerator (1). The denominator stays the same
(3x4+1)/4 = 13/4
Now, we can multiply
[tex]\frac{13}{4}\text{ }\times\frac{2}{3}[/tex]Multiply the top number and the bottom numbers:
[tex]\frac{(13\times2)}{(4\times3)}[/tex][tex]\frac{26}{12}[/tex]Simplify by 2
[tex]\frac{13}{6}[/tex]
