Answer:
a
. eight tenths of her cookies
Explanation:
Let the total number of Lakesha's cookies be represented by x.
So that;
She gave three tenths to Bailey = [tex]\frac{3}{10}[/tex] of x
= [tex]\frac{3x}{10}[/tex]
She gave five tenths to Helen = [tex]\frac{5}{10}[/tex] of x
= [tex]\frac{5x}{10}[/tex]
Fraction of Lakesha's cookies given away = [tex]\frac{3x}{10}[/tex] + [tex]\frac{5x}{10}[/tex]
= [tex]\frac{3x+ 5x}{10}[/tex]
= [tex]\frac{8x}{10}[/tex]
Thus, the fraction of cookies given away by Lakesha is [tex]\frac{8}{10}[/tex].
