Answer:

Step-by-step explanation:

First question

x = 4/10 = 0.4 (type 0.4)

Second Question

x = 0.04/10 = 4/1000 = 0.004 (type 0.004)

Third Question

x = 0.4/10 = 4/100 = 0.04 (type 0.04)

Fourth Question

x = 40/10 = 4 (type 4)
1)
4 = 10 x

x = ⁴/₁₀ = ²/₅
x = 0.4

------------------
2)
0.04 = 10 x

x = ⁰.⁰⁴ / ₁₀
x = 0.004
-----------------
3)
0.4 = 10 x

x = ⁰'⁴/₁₀

x = 0.04
-----------------
4)
40 = 10 x

x = ⁴⁰/₁₀
x = 4
