Question

Answer these questions. 45% of 40 is 18% of what number?

Answer 1

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

$\Rightarrow \dfrac{45}{100} \times 40\\\Rightarrow \dfrac{1800}{100}\\\Rightarrow 18 ...... (1)$

Taking RHS(Right Hand Side):

18% of x

$\Rightarrow \dfrac{18}{100} \times x\\\Rightarrow 0.18 \times x ...... (2)$

Equating (1) and (2):

$18 = 0.18 \times x\\\Rightarrow x= \dfrac{1800}{18}\\\Rightarrow x = 100$

Hence, 45% of 40 is 18% of 100.
