Solve I=1/20+2/5+3/10=

$$I = \frac { 1 } { 20 } + \frac { 2 } { 5 } + \frac { 3 } { 10 } =$$

Solve for I

$$I=\frac{3}{4}=0.75$$

Steps for Solving Linear Equation

Least common multiple of 20 and 5 is 20. Convert \frac{1}{20} and \frac{2}{5} to fractions with denominator 20.

$$I=\frac{1}{20}+\frac{8}{20}+\frac{3}{10}$$

Since \frac{1}{20} and \frac{8}{20} have the same denominator, add them by adding their numerators.

$$I=\frac{1+8}{20}+\frac{3}{10}$$

Add 1 and 8 to get 9.

$$I=\frac{9}{20}+\frac{3}{10}$$

Least common multiple of 20 and 10 is 20. Convert \frac{9}{20} and \frac{3}{10} to fractions with denominator 20.

$$I=\frac{9}{20}+\frac{6}{20}$$

Since \frac{9}{20} and \frac{6}{20} have the same denominator, add them by adding their numerators.

$$I=\frac{9+6}{20}$$

Add 9 and 6 to get 15.

$$I=\frac{15}{20}$$

Reduce the fraction \frac{15}{20} to lowest terms by extracting and canceling out 5.

$$I=\frac{3}{4}$$

Assign I

$$I≔\frac{3}{4}$$
