Answer 7

You can find equivalent fractions by multiplying the numerator and denominator by the same number. Let's multiply our denominator and numerator by 10 to eliminate the decimal.

\(2000 \div 0.2 = \dfrac{8000}{0.2} = \dfrac{8000 \times 10}{0.2 \times 10} = \dfrac{80,000}{2}\)

Now youj can do the division easily.
What is \(80,000 \div 2\) ?
