To solve this problem, we simply have to use ratio and
proportion. We know that for every 5 cm, we have 1 m therefore the factor to
use is:
5 cm / 1 m
SO for a table length of 1.4 m, the model length should
be:
model = (5 cm / 1 m) * 1.4 m
model = 7 cm
Answer:
7 cm
The answer is $1.80. You would take 25% of 3, which is 75, and subtract it from 3. That leaves you with $2.25, which you take 20% off, which is 0.45, and subtract that from 2.25. That leaves you with a grand total of $1.80. Hope that this helped!
Because ft is bigger than inches and 1ft is 12 inches
