Question

Lakesha gave three tenths of her cookies to Bailey and five tenths of her cookies to Helen. What fraction of her cookies did Lakesha give away?

a
eight tenths of her cookies

b
five tenths of her cookies

c
three tenths of her cookies

d
two tenths of her cookies

Answer 1

a . eight tenths of her cookies

Step-by-step explanation:

Let the total number of Lakesha's cookies be represented by x.

So that;

She gave three tenths to Bailey =
`(3)/(10)` of x

=
`(3x)/(10)`

She gave five tenths to Helen =
`(5)/(10)` of x

=
`(5x)/(10)`

Fraction of Lakesha's cookies given away =
`(3x)/(10)` +
`(5x)/(10)`

=
`(3x+ 5x)/(10)`

=
`(8x)/(10)`

Thus, the fraction of cookies given away by Lakesha is
`(8)/(10)`.
