Question

5/2=d−2/4

What does d=?

Answer 1

d = 3

Explanation:

`(5)/(2)=d-(2)/(4)\qquad\left/(2)/(4)=(2:2)/(4:2)=(1)/(2)\right/\\\\(5)/(2)=d-(1)/(2)\qquad\text{add}\ (1)/(2)\ \text{to both sides}\\\\(5)/(2)+(1)/(2)=d-(1)/(2)+(1)/(2)\\\\(5+1)/(2)=d\\\\(6)/(2)=d\to d=3`

Answer 2

Use GCF to find the denominator, then solve by adding 4/8 to the other side and simplify.
