Answer:
45% of 40 is 18% of 100
Step-by-step explanation:
Let 45% of 40 = 18% of x .
Taking LHS (Left Hand Side):
45% of 40
[tex]\Rightarrow \dfrac{45}{100} \times 40\\\Rightarrow \dfrac{1800}{100}\\\Rightarrow 18 ...... (1)[/tex]
Taking RHS(Right Hand Side):
18% of x
[tex]\Rightarrow \dfrac{18}{100} \times x\\\Rightarrow 0.18 \times x ...... (2)[/tex]
Equating (1) and (2):
[tex]18 = 0.18 \times x\\\Rightarrow x= \dfrac{1800}{18}\\\Rightarrow x = 100[/tex]
Hence, 45% of 40 is 18% of 100.
