Answer:

448 ÷ 320 = 1.4

Step-by-step explanation:

The division expression is:

448 ÷ 320

This can be rewritten as:


(448)/(320)

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


(32*14)/(32*10)

Since 32 is common to the numerator and denominator, it can cancel out

The resulting expression is:


(14)/(10)
\begin{gathered} (14)/(10)=1(4)/(10) \\ =1\text{ + }0.4 \\ =\text{ 1.4} \end{gathered}

Therefore, 448 ÷ 320 = 1.4
