X/2+X/3+X/5=6.2 FIND A COMMON DENOMINATOR (30)
(15X+10X+6X)/30=6.2
31X/30=6.2
31X=186
X=186/31
X=6
1/2*6=3 ONE SIDE
1/3*6=2 SECOND SIDE
1/5*6=6/5=1.2 THIRD SIDE
PROOF
3+2+1.2=6.2
6.2=6.2

Since you know the ratio of the three sides of the triangle ((1/2):(1/3):(1/5)) you then need to find a common multiplier so that when multiply each of these ratios and add the results, you will get the perimeter of 6.2
Let's call this common multiplier, x.
Simplify this and solve for x. Multiply through by the LCD of 30.
Simplify this.

Divide both sides by 31.

So the measures of the three sides are:
= 3
= 2
= 1.2
