Answer 1

Answer:

Tony, Adela, Ruben. Pang

Step-by-step explanation:

Given

Average Age = 11 years

Difference from Age:

$Adela: 0.75 year$

$Tony: 1\frac{1}{10}\ years$

$Pang: -0.8 year$

$Ruben: -\frac{1}{2}\ year$

Required

Order their age from least to highest

Convert the age difference to decimal

$Adela: 0.75\ year$

$Tony: 1.1\ years$

$Pang: -0.8\ year$

$Ruben: -0.5\ year$

Subtract the age difference from the Average age to get their actual age

$Adela: 11 - 0.75 = 10.25\ years$

$Tony: 11 - 1.1 = 9.9\ years$

$Pang: 11 - (-0.8) = 11+0.8 = 11.8\ years$

$Ruben:11 - (-0.5) = 11 + 0.5 = 11.5\ years$

From the result above, we can now order them from least to highest:

Tony, Adela, Ruben. Pang
