How do you work out 12 divided by 35.16?

Answer 1

0.3413

Answer 2

Make the divisor a whole number by multiplying it by a power of 10; then multiply the dividend by the same power of 10. Now you have a whole number divisor and so can do the division as normal (by long division).

The divisor 35.16 has 2 digits after the decimal point, so multiply by 10² = 100

→ 36.16 × 100 = 3516

Also multiply the dividend 12 by 10²

→ 12 × 100 = 1200

→ 12 ÷ 35.16 = 1200 ÷ 3516

You can either divide that directly or simplify it by noticing that hcf(1200, 3516) = 12, giving:

1200 ÷ 3516 = (1200÷12) ÷ (3516÷12) = 100 ÷ 293

Using long division you will get 12 ÷ 35.16 ≈ 0.341
