Question

Compute the following mentally; find the exact answers (explain thinking in words)

3 1/2 divided by 1/2

Answer 1

Hello!

Step-by-step explanation:

First, you convert by the mixed numbers into improper fractions.

`3(1)/(2)= (7)/(2)`

Then, apply by the fraction rule.

`(a)/(b)/(c)/(d)= (a)/(b)* (d)/(c)`

`(7)/(2)* (2)/(1)`

Next, you had to cancel by the 2.

`(7)/(1)`

Finally, divide by the numbers or multiply by the numbers too.

`(7)/(1)=7`

Answer:
`\boxed{=7}`

Hope this helps!

Thanks!
