Answer:
a piston chamber in a steam or internal combustion engine.
Ok so to find best price, find cost per unit or unit rate
so what we do is
(amount of flower x batches)/x and divide out
when dividng fractions, just invert the second one and multiply, example
3/4 divided by 5/6=3/4 times 6/5=18/20 so
A.1/2 cup for 2/3, (1/2)/(2/3), 1/2 times 3/2, 3/4 cup per batch
B. 1/3 per 1/4 batch, (1/3)/(1/4), 1/3 times 4/1, 4/3 cup per batch=1 and 1/3
C. 2/3 cup for 1/2 batch, (2/3)/(1/2), 2/3 times 2/1, 4/3 cp per batch=1 and 1/3
D. 3/4 cup per 2/3 batch, (3/4)/(2/3), 3/4 times 3/2, 9/8 cup per batch=1 and 18/
lowest unit rate is 3/4 cup per batch since others are greater than 1
answer is A
The second answer choice matches the number line
