Question

1. Rajeev is is convinced that he and Catarina have the same amount of plants in their

homes. Rajeev has four cacti, 12 zucchini plants, and 10 air plants. Catarina has 12
cacti, 9 air plants, and 4 daisy plants. Is Rajeev correct? Write an equation or
inequality to show your thinking,

Answer 1

Rajeev is incorrect.

Explanation:

Rajeev has 26 (4+12+10) plants in his home. Catarina has 25 (12+9+4) plants in her home.

From this, we get:

4+12+10 > 12+9+4

because:

26>25

So, Rajeev has more plants than Catarina, rather than the same amount.

You could use the bolded inequality to show your thinking.

Answer 2

4 + 12 + 10 = 12 + 9 + 4
26 = 25
No Rajeev is wrong since he has one more plant than Catarina
