(Re Post) Answer these three questions: 1. Draw 16 stairs. put them equally into 2 sets. how many stairs are there in each set?

2. Abel drew some triangles. his drawing had 21 vertices. how many triangles did he draw? write a division sentence to answer this question.

30 ÷ 6 = 5
write a related multiplication sentence.

did you get the answer?

8.75

how-to:

first, we need to find what we have to work with.

since i know that we have 7 (years) and 0.8 (inches), we can use these to solve and find the equation!

secondly, what you want to do, is see that we need to know how much growth out of the 0.8 inches he got in only 1 year, instead of 7 years.

let's try to divide.

7 ÷ 0.8 = 8.75
