How many times greater is 7 x 10^6 than 4.5 x 10^-1
kipiarov [429]

Let us assume that : 7 × 10⁶ is P times Greater than 4.5 × 10⁻¹

It means when we Multiply P with 4.5 × 10⁻¹, We should get 7 × 10⁶

⇒ (P × 4.5 × 10⁻¹) = 7 × 10⁶

\mathsf{\implies P = (\dfrac{7 \times 10^6}{4.5 \times 10^-^1})}

\mathsf{\implies P = 1.56 \times 10^7}

⇒ 7 × 10⁶ is 1.56 × 10⁷ times Greater than 4.5 × 10⁻¹
