Question

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

Answer 1

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
