2. In making a palamig, you need to mix [tex]\( 2 \frac{1}{2} \)[/tex] pitchers of pineapple juice and [tex]\( 4 \frac{3}{4} \)[/tex] pitchers of water. How much is the mixture in total?

3. Zailene wants to make two kinds of kakanin, puto and kutsinta. The puto recipe needs [tex]\( 3 \frac{2}{5} \)[/tex] cups of flour, while the kutsinta recipe needs [tex]\( 5 \frac{1}{4} \)[/tex] cups of flour. How many cups of flour will be needed in all?



Answer :

Certainly! Let's break down each of the problems with detailed, step-by-step solutions.

### Problem 1: Perimeter of the triangle

1. To find the perimeter of a triangle with sides [tex]\( 5 \frac{1}{2} \)[/tex] cm, [tex]\( 7 \frac{3}{5} \)[/tex] cm, and [tex]\( 3 \frac{1}{4} \)[/tex] cm, we first convert each mixed number to improper fractions or to their decimal equivalents.

2. [tex]\( 5 \frac{1}{2} \)[/tex] can be converted to 5.5 cm
[tex]\( 7 \frac{3}{5} \)[/tex] can be converted to 7.6 cm
[tex]\( 3 \frac{1}{4} \)[/tex] can be converted to 3.25 cm

3. Add these values to find the perimeter:
[tex]\[ 5.5 + 7.6 + 3.25 = 16.35 \text{ cm} \][/tex]

So, the perimeter of the triangle is [tex]\( \boxed{16.35 \text{ cm}} \)[/tex].

### Problem 2: Total mixture for making palamig

1. To find the total mixture of pineapple juice and water, we convert the quantities to their decimal equivalents.

2. [tex]\( 2 \frac{1}{2} \)[/tex] can be converted to 2.5 pitchers
[tex]\( 4 \frac{3}{4} \)[/tex] can be converted to 4.75 pitchers

3. Add these values to get the total mixture:
[tex]\[ 2.5 + 4.75 = 7.25 \text{ pitchers} \][/tex]

So, the total mixture is [tex]\( \boxed{7.25 \text{ pitchers}} \)[/tex].

### Problem 3: Total cups of flour needed

1. To find the total cups of flour needed for making puto and kutsinta, we convert the quantities to their decimal equivalents.

2. [tex]\( 3 \frac{2}{5} \)[/tex] can be converted to 3.4 cups
[tex]\( 5 \frac{1}{4} \)[/tex] can be converted to 5.25 cups

3. Add these values to get the total flour needed:
[tex]\[ 3.4 + 5.25 = 8.65 \text{ cups} \][/tex]

So, the total cups of flour needed is [tex]\( \boxed{8.65 \text{ cups}} \)[/tex].

Each problem above has been carefully resolved by converting mixed numbers to decimals and then summing them up to get the desired result.
