1. In a class of 45,  are boys. How many are girls?

a. What is asked in the problem? How many are girls

b. What are the given facts?  45, [tex]\frac{4}{9}[/tex]    

c. What operations are to be used? Multiplication and Division

d. What is the number sentence? [tex]45 \times (1 - \frac{4}{9}) = n[/tex]

e. What is the solution?

  • [tex]45\times \left(1-\frac{4}{9}\right)[/tex]
  • Follow the PEMDAS order of operations
  • Calculate within parentheses [tex](1-\frac{4}{9}) = \frac{5}{9}[/tex]
  • [tex]=45\times \frac{5}{9}[/tex]
  • Multiply and divide: [tex]45 \times \frac{5}{9} =[/tex]
  • [tex]\boxed{\green{= 25}}[/tex]

f. What is the complete answer? [tex]\boxed{= 25}[/tex]

2. Eggplants are sold at Php35 per kilogram and ampalaya at Php60  per kilogram. How much would you pay if you were to buy  5  kilograms of eggplants and 2  kilograms of ampalaya?

a. What is asked in the problem? How much would you pay if you were to buy  5  kilograms of eggplants and 2  kilograms of ampalaya?

b. What are the given facts? Eggplant Php 35 per kg and ampalaya Php 60 per kg [tex]5 \frac{1}{2}[/tex] kg eggplant, [tex]2 \frac{1}{3}[/tex] kg of ampalaya

c. What operations are to be used? Multiplication and Addition

d. What is the number sentence? [tex]\left(5\frac{1}{2}\cdot \:35\right)+\left(2\frac{1}{3}\cdot \:60\right) = n[/tex]

e. What is the solution?

  • [tex]\left(5\frac{1}{2}\cdot \:35\right)+\left(2\frac{1}{3}\cdot \:60\right)[/tex]
  • Convert mixed numbers to improper fractions: [tex]5 \frac{1}{2} = \frac{11}{2}[/tex]
  • Convert mixed numbers to improper fractions: [tex]2 \frac{1}{3} = \frac{7}{3}[/tex]  
  • [tex]=\left(\frac{11}{2}\cdot \:35\right)+\left(\frac{7}{3}\cdot \:60\right)[/tex]
  • Follow the PEMDAS order of operations
  • Calculate within parentheses:  [tex](\frac{11}{2} \cdot 35) = \frac{385}{2}[/tex]
  • Calculate within parentheses: [tex](\frac{7}{3} \cdot 60) = 140[/tex]
  • [tex]=\frac{385}{2}+140[/tex]
  • Add and subtract: [tex]\frac{385}{2} + 140 = \frac{665}{2}[/tex]
  • Convert improper fraction to mixed numbers: [tex]\frac{665}{2} = 332\frac{1}{2}[/tex]
  • Convert mixed numbers to decimals: [tex]332\frac{1}{2} = 332.5[/tex]
  • [tex]\boxed{\green{332.5}}[/tex]

f. What is the complete answer? [tex]\boxed{332.5}[/tex]
