hello, I have an exam tomorrow but I do not understand how to do the division parts.

448 ÷ 320 = 1.4
Explanation:The division expression is:
448 ÷ 320
This can be rewritten as:
[tex]\frac{448}{320}[/tex]Given: 32 x 14 = 448
Also, 32 x 10 = 320
Therefore, replace 448 by 32 x 14 and also replace 320 by 32 x 10
[tex]\frac{32\times14}{32\times10}[/tex]Since 32 is common to the numerator and denominator, it can cancel out
The resulting expression is:
[tex]\frac{14}{10}[/tex][tex]\begin{gathered} \frac{14}{10}=1\frac{4}{10} \\ =1\text{ + }0.4 \\ =\text{ 1.4} \end{gathered}[/tex]Therefore, 448 ÷ 320 = 1.4
