What is 2.9 as a fraction. Explain how you got your answer.

Answer 1

2.9 can be written as a fraction as follows:

2.9 = 29/10

To convert a decimal to a fraction, we first write the decimal as a fraction with the same denominator as 10, which is a power of 10. Then, we simplify the fraction as much as possible.

We can write 2.9 as 2 + 0.9. Since 0.9 is equal to 9/10, we can write:

2.9 = 2 + 9/10

To write this as a single fraction, we need to find a common denominator. The least common multiple of 10 is 10 itself, so we can write:

2.9 = 2*(10/10) + 9/10
= 20/10 + 9/10

Now, we can add the fractions:

2.9 = (20 + 9)/10
= 29/10

Therefore, 2.9 as a fraction is 29/10.
