Answer:
Zailene needs
cups of flour.
Step-by-step explanation:
ADDITION OF MIXED FRACTIONS
To get the total number of cups of flour for Puto and Kutsinta, we need to add the
cups of flour for Puto and the 
of cups of flour for Kutsinta.
1ST METHOD:
Step 1: Separately, we add the whole numbers.
Step 2: To add fractions, we take the Least Common Multiple (LCM) of the denominators and change the fractions into similar fractions.
To get the LCM of the denominators, we list all the multiples of 5 and 4.
Therefore, the least common multiple is 20.
Step 3: Find the sum of the whole numbers and the fractions in the simplest form.
= (3 + 5) +
+ 
= 8 +![[\frac{2}{5} +\frac{1}{4} =\frac{8+5}{20} =\frac{13}{20}]](https://tex.z-dn.net/?f=%5B%5Cfrac%7B2%7D%7B5%7D%20%2B%5Cfrac%7B1%7D%7B4%7D%20%3D%5Cfrac%7B8%2B5%7D%7B20%7D%20%3D%5Cfrac%7B13%7D%7B20%7D%5D "[\frac{2}{5} +\frac{1}{4} =\frac{8+5}{20} =\frac{13}{20}]")
= 8 +
= 8
2nd Method:
Step 1: Change the mixed fractions into improper fractions.
= (3 x 5) +
+ (4 x 5) + 
Step 2: We take the Least Common Multiple (LCM) of the denominators and change the fractions into like fractions.
Again, we list all the multiples of 5 and 4.
The least common multiple is 20.
Step 3: Add and express the sum to its simplest form.
