Answer 2

$\LARGE{\underline{\underline{\pink{\sf{Required \: Answer:–}}}}}$

Slices John had = 8 slice

Annie got = ½

Ruby got = ¼

Number of slices Annie got

$\implies \frac{1}{2} \times 8$

$\implies \frac{1}{ \cancel{2}} \times \cancel{8}$

$\implies 4$

Pieces remaining after giving slices to Annie

$\implies 8 - 4$

$\implies 4$

Number of pieces Ruby got

$\implies \frac{1}{4} \times 4$

$\implies \frac{1}{ \cancel{4}} \times \cancel{4}$

$\implies 1$

So,

No. of slices Annie got = 4

No. of slices Ruby got = 1

Total = 4 + 1 = 5

Pieces remaining after giving to Ruby and Annie

$\implies 8 - 5$

$\implies 3$

Hence , 3 slices are left by John
