Answer:

The decimal of 9/12 is 0.75.

Step-by-step explanation:

You can first reduce this fraction by dividing both the numerator and denominator by the Greatest Common Factor of 9 and 12 using

GCF (9, 12) = 3

9 ÷ 3 / 12 ÷ 3 = 3/4

We know that

3/4

is the same as

3 ÷ 4

Then using long division for 3 divided by 4 and rounding to a max of 3 decimal places gives us

= 0.75
