Solve 2000000(1+4r)=2240000

$$2000000 ( 1 + 4 r ) = 2240000$$

Solve for r

$$r=\frac{3}{100}=0.03$$

Steps for Solving Linear Equation

Divide both sides by 2000000.

$$1+4r=\frac{2240000}{2000000}$$

Reduce the fraction \frac{2240000}{2000000} to lowest terms by extracting and canceling out 80000.

$$1+4r=\frac{28}{25}$$

Subtract 1 from both sides.

$$4r=\frac{28}{25}-1$$

Convert 1 to fraction \frac{25}{25}.

$$4r=\frac{28}{25}-\frac{25}{25}$$

Since \frac{28}{25} and \frac{25}{25} have the same denominator, subtract them by subtracting their numerators.

$$4r=\frac{28-25}{25}$$

Subtract 25 from 28 to get 3.

$$4r=\frac{3}{25}$$

Divide both sides by 4.

$$r=\frac{\frac{3}{25}}{4}$$

Express \frac{\frac{3}{25}}{4} as a single fraction.

$$r=\frac{3}{25\times 4}$$

Multiply 25 and 4 to get 100.

$$r=\frac{3}{100}$$
