Algebra Difficulty 1.3 Junior Find the answer Canada

Olivia cuts a $42$ cm length
of string into $2$ cm pieces. Jeff
cuts a $42$ cm length of string into
$3$ cm pieces. How many more pieces
of string does Olivia have than Jeff?

Pick one

Solution

Since $\frac{42\text{ cm}}{2\text{ cm}}=21$ , then Olivia cuts her string into 21 pieces.

Since $\frac{42\text{ cm}}{3\text{ cm}}=14$ , then Jeff cuts his string into 14 pieces.

Therefore, Olivia has $21-14=7$ more
pieces of string than Jeff.
