Chapter 2: Q. 80 (page 113)

For the equation $0.35 x + 2.1 = 3.85$ , how do you clear the decimal ?

Short Answer

Expert verified

To clear the decimal, multiply both the sides of the equation by $100$ .

Step by step solution

Step 1. Decimals given in the question can be written as a fraction,

$0.35 = \frac{35}{100}$

$2.1 = \frac{210}{100}$

$3.85 = \frac{385}{100}$

Step 2. Rewrite the equation.

Equation can be rewritten as,

$\frac{35}{100} x + \frac{210}{100} = \frac{385}{100}$

Step 3. Find LCD of the fractions.

LCD = $100$

Step 4. Multiply the equation with LCD,

$100 (\frac{35}{100} x + \frac{210}{100}) = (\frac{385}{100}) \times 100$

Step 5. Solve the equation,

$35 x + 210 = 385$

Hence, to remove the decimal multiply the equation by LCD $100$ .
