Question

How do you evaluate `\frac{7}{8}\div .25`?

Answer 1

See a solution process below:

Explanation:

First, we can rewrite: `0.25 = 25/100 = 1/4`

Next, we can rewrite the problem as:

`7/8 -: 1/4 => (7/8)/(1/4)`

Now, we can use this rule for dividing fractions to evaluate the expression:

`(color(red)(a)/color(blue)(b))/(color(green)(c)/color(purple)(d)) = (color(red)(a) xx color(purple)(d))/(color(blue)(b) xx color(green)(c))`

`(color(red)(7)/color(blue)(8))/(color(green)(1)/color(purple)(4)) = (color(red)(7) xx color(purple)(4))/(color(blue)(8) xx color(green)(1)) = (color(red)(7) xx cancel(color(purple)(4)))/(cancel(color(blue)(8))2 xx color(green)(1)) = 7/2`

Answer 2

`3 1/2` or`3.5`

Explanation:

`7/8-:0.25`

`:.=7/8-:1/4`

`:.=7/cancel8^2xxcancel4^1/1`

`:.=7/2`

`:.=3 1/2` or`3.5`

Answer 3

`3 1/2` or`3.5`

Explanation:

`7/8-:0.25`

`:.=7/8-:1/4`

`:.=7/cancel8^2xxcancel4^1/1`

`:.=7/2`

`:.=3 1/2` or`3.5`
