Answer:

0.0175

Explanation:

To divide 0.21 by 12 without a calculator, you can use long division. Here's how you can do it:

Write 0.21 as a fraction: 21/100

Place the fraction over the divisor (12): 21/100 ÷ 12

Multiply both sides of the equation by 100 to get rid of the decimal point in the numerator: 21 ÷ 100 · 100 ÷ 12

Simplify by canceling out the common factor of 100: 21 ÷ 12

Divide 12 into 21: 1 remainder 9

Write the remainder (9) as a fraction over the divisor (12) to get the final answer: 0.0175
