Solve A=123(1+0.13*4/12

$$A = 123 ( 1 + 0.13 \cdot 4 / 12$$

Solve for A

$$A=128.33$$

Steps for Solving Linear Equation

Reduce the fraction \frac{4}{12} to lowest terms by extracting and canceling out 4.

$$A=123\left(1+0.13\times \frac{1}{3}\right)$$

Convert decimal number 0.13 to fraction \frac{13}{100}.

$$A=123\left(1+\frac{13}{100}\times \frac{1}{3}\right)$$

Multiply \frac{13}{100} times \frac{1}{3} by multiplying numerator times numerator and denominator times denominator.

$$A=123\left(1+\frac{13\times 1}{100\times 3}\right)$$

Do the multiplications in the fraction \frac{13\times 1}{100\times 3}.

$$A=123\left(1+\frac{13}{300}\right)$$

Convert 1 to fraction \frac{300}{300}.

$$A=123\left(\frac{300}{300}+\frac{13}{300}\right)$$

Since \frac{300}{300} and \frac{13}{300} have the same denominator, add them by adding their numerators.

$$A=123\times \frac{300+13}{300}$$

Add 300 and 13 to get 313.

$$A=123\times \frac{313}{300}$$

Express 123\times \frac{313}{300} as a single fraction.

$$A=\frac{123\times 313}{300}$$

Multiply 123 and 313 to get 38499.

$$A=\frac{38499}{300}$$

Reduce the fraction \frac{38499}{300} to lowest terms by extracting and canceling out 3.

$$A=\frac{12833}{100}$$

Assign A

$$A≔128.33$$
