Answer:
2.9 = 29/10 = 2 9/10
Explanation:
Step 1:
Write down the number as a fraction of one:
2.9 = 2.91
Step 2:
Multiply both top and bottom by 10 for every number after the decimal point:
As we have 1 number after the decimal point, we multiply both the numerator and denominator by 10.
So, 2.91 = (2.9 × 10)(1 × 10) = 29/10.
(This fraction is already reduced, We can't reduce it any further).
As the numerator is greater than the denominator, we have an IMPROPER fraction, so we can also express it as a MIXED NUMBER, thus 29/10 is also equal to 2 9/10 when expressed as a mixed number.
