A recipe shows that yeast needed for a bread recipe 2 1/3 ounces. Which of the following decimals is eqivalent to this number?
Olin [163]
The correct answer is B. 2.3. 

For us to know the equivalent decimals of a fraction, you have to use the numerator as the dividend, and the denominator will be your divisor.

The equation will be:

2 + ( 1 / 3 ) 
2 + (0.33333333)
= 2.333333

If you'll have it rounded off, you'll get the answer 2.3.
