Question

$\square$
$= \frac{25 \cdot 1}{3 \cdot 10}$
$\square$

Explanation:

Step1: Identify original fraction

The original expression leading to $\frac{25 \cdot 1}{3 \cdot 10}$ is $\frac{25}{10} \times \frac{1}{3}$, so the first box is $\frac{25}{10} \times \frac{1}{3}$.

Step2: Calculate numerator and denominator

Multiply terms in numerator and denominator:
Numerator: $25 \cdot 1 = 25$
Denominator: $3 \cdot 10 = 30$
Simplify the fraction: $\frac{25}{30} = \frac{5}{6}$

Answer:

Top box: $\boldsymbol{\frac{25}{10} \times \frac{1}{3}}$
Bottom box: $\boldsymbol{\frac{5}{6}}$
