Problem 1:
Asked: The amount of liters of gasoline are needed.
Given: A car travels 11 ½ km for every loiter of gasoline. There was a 46-km trip.
Operation: Division
Number Sentence: 46÷11 ½=n
Solution:
[tex]46 \div 11 \: \frac{1}{2} = n[/tex]
[tex]n = 46 \div \frac{23}{2} [/tex]
[tex]n = 46 \times \frac{2}{23} [/tex]
[tex]n = 2 \times \frac{2}{1} [/tex]
[tex]n = \frac{4}{1} [/tex]
[tex]n = 4[/tex]
Answer: 4 liters of gasoline
Problem 2:
Asked: The amount of hectares of farm could he plow using the same machine.
Given: Using a modern machine, it takes a farmer ⅓ hour to plow ¾ hectare of farm. There was a 1 hour.
Operation: Division
Number Sentence: ¾÷⅓=x
Solution:
[tex] \frac{3}{4} \div \frac{1}{3} = x[/tex]
[tex]x = \frac{3}{4} \times \frac{3}{1} [/tex]
[tex]x = \frac{9}{4} [/tex]
[tex]x = 2 \: \frac{1}{4} [/tex]
Answer:
2 ¼ hectares of farm
