Question

Man and Sato we’re building a coffee table using 4 inch tiles. Nan used 30 tiles and Sato uses half as many. How many total tiles did they use?

Answer 1

Here, we have to add Nan's tiles to Sato's tile usage, which is half of Nan's.

We can solve this expression:

30 + 30 (0.5)
30 + 15
= 45

Therefore, both used a total of 45 tiles! :)
