1/2 of 5 is 3, so 1/2 of 10 is 6; (1/3)/(1/2)=2/3 => 1/3 of 10 is 2/3 of 6 is 4.

  • (1/2) = (3/5)
  • (1/2) * (2/3) = (2/3) * (3/5) = (1/3)
  • 10 * (6/15) = 4

1 2 × 5 = 2.5 ; ⌈ 2.5 ⌉ = 3 \frac{1}{2}×5=2.5;~{\lceil}2.5{\rceil}={\boxed{3}}

1 3 × 10 = 3. 3 ‾ ; ⌈ 3. 3 ‾ ⌉ = 4 \frac{1}{3}×10=3.{\overline{3}};~{\lceil}3.{\overline{3}}{\rceil}={\color{#3D99F6}{\boxed{4}}}

Hence the answer is 4 \color{#3D99F6}{\boxed{4}} .

Note: ⌈ . ⌉ \lceil{.}{\rceil} represented as Ceilling floor .
