If the base of the triangle is 3/5 and the height is 2/3, what is the initial expression for the area?

• (3/5) + (2/3) / 2

• (3/5) * (2/3) / 2

• (3/5) - (2/3) / 2

• (3/5) / (2/3) / 2

Can any numbers be simplified in the fraction (3/5) * (2/3)?

• No, it cannot be simplified.

• Yes, the 3s can be cancelled out.

• Yes, the 2s can be cancelled out.

• Yes, the 5s can be cancelled out.
