Question

1/4 + 1/4 + 1/4; 2.544 + 16

Explanation:

Step1: Simplify the first expression

The first expression is $\frac{4}{9} + \frac{4}{9} + \frac{4}{15}$. First, add the two $\frac{4}{9}$ terms: $\frac{4}{9}+\frac{4}{9}=\frac{8}{9}$. Now the expression becomes $\frac{8}{9}+\frac{4}{15}$. Find a common denominator, which is 45. Convert the fractions: $\frac{8}{9}=\frac{40}{45}$ and $\frac{4}{15}=\frac{12}{45}$. Then add them: $\frac{40}{45}+\frac{12}{45}=\frac{52}{45}=1\frac{7}{45}$.

Step2: Simplify the second expression

The second expression is $2.544\div16$. Divide 2.544 by 16: $2.544\div16 = 0.159$.

Answer:

First expression result: $\frac{52}{45}$ (or $1\frac{7}{45}$), Second expression result: $0.159$
