Question

suzie always looks forward to her family camping trips. on this trip, she started recording how much propane fuel they used during each meal. use the line plot to answer the question below. amount of propane fuel line plot with xs at 1, 1 1/4, 1 1/2, 1 3/4 cans: 1 x at 1, 1 x at 1 1/4, 2 xs at 1 1/2, 3 xs at 1 3/4 how much propane fuel did they use in all? write your answer as a fraction, mixed number, or whole number. blank cans

Explanation:

Step1: Count propane per amount

• 1 can: 1 mark, total: $1 \times 1 = 1$
• $1\frac{1}{4}$ cans: 1 mark, total: $1 \times 1\frac{1}{4} = 1\frac{1}{4}$
• $1\frac{1}{2}$ cans: 2 marks, total: $2 \times 1\frac{1}{2} = 3$
• $1\frac{3}{4}$ cans: 3 marks, total: $3 \times 1\frac{3}{4} = \frac{21}{4}$

Step2: Convert to improper fractions

$1 = \frac{4}{4}$, $1\frac{1}{4} = \frac{5}{4}$, $3 = \frac{12}{4}$

Step3: Sum all propane amounts

$\frac{4}{4} + \frac{5}{4} + \frac{12}{4} + \frac{21}{4} = \frac{4+5+12+21}{4} = \frac{42}{4}$

Step4: Simplify the fraction

$\frac{42}{4} = \frac{21}{2} = 10\frac{1}{2}$

Answer:

$10\frac{1}{2}$ cans
