Draw a model on grid paper to find the product of 3 and 1.4. What is the product?

4.2

Step-by-step explanation:

I don't have graph paper at the moment but you could put this on graph paper.

3 times 1.4 means 1.4 + 1.4 + 1.4

*️⃣*️⃣*️⃣ each box equals to 1.4.

Now you just have to add the boxes.

1.4 + 1.4 + 1.4 = 4.2
