Answer 1

Question:

Rewrite the expression 1/2p - (1 - 1/4p) without parentheses.​

Solution:

Consider the following expression:

`(1)/(2)\text{ p - (1-}(1)/(4)p\text{)}`

putting together like terms, we get:

`(1)/(2)p\text{ + }(1)/(4)p-1`

this is equivalent to:

`\frac{2p\text{ + p}}{4}-1`

finally, this is equivalent to:

`\frac{3\text{ p}}{4}-1`

then, the correct answer is:

`\frac{3\text{ p}}{4}-1`
