1. a common denominator is a number that is the denominator

of two or more fractions. in $\frac{1}{4}$ and $\frac{3}{4}$, the common denominator is 4.
circle the fractions with common denominators.
$\frac{6}{15}$ $\frac{6}{12}$ $\frac{3}{15}$ $\frac{1}{2}$

1. to partition means to divide into parts.

partition the rectangle on the left into fifths.
the rectangle in the middle is partitioned into _ _ _ _ _ _.
partition the rectangle on the right into tenths.

Explanation:

Step1: Identify common denominators

Check denominators of fractions. For \(\frac{6}{15}\), denominator is \(15\); for \(\frac{6}{12}\), denominator is \(12\); for \(\frac{3}{15}\), denominator is \(15\); for \(\frac{1}{2}\), denominator is \(2\).

Step2: Circle fractions with same denominators

Since \(\frac{6}{15}\) and \(\frac{3}{15}\) have denominator \(15\), they are circled.

Answer:

\(\frac{6}{15}\) and \(\frac{3}{15}\) are circled.
