Answer:
1.5 cm = .015 meters
3.5 / .015 = 233.33
So, in his scale everything will be 233.33 times smaller.
So, if the building is 180 meters tall, his model will be (180 / 233.33) meters tall, which equals 0.771439592 meters which equals
77.14 centimeters.

Answer:
Esmerelda did not use the reciprocal of the divisor.
Step-by-step explanation:
A complex fraction is another way to show division of two fractions. In this case, we are dividing -5 1/4 by 3/2.
We first convert -5 1/4 to an improper fraction. To do this, multiply the whole number by the denominator; this gives us -5(4) = -20. Then add the -1 (negative since the fraction is negative); this gives us -21/4.
This means we are dividing -21/4 by 3/2.
To divide fractions, we multiply by the reciprocal; this means we flip the second fraction and multiply. We would then multiply -21/4 by 2/3. This is the step Esmerelda did not do.
Answer:
38/5
Step-by-step explanation:
15 x 3 = 45 + 3 = 48/15
then 4 + 5 = 20 + 2 = 22/5
22/5 + 48/15 = ?
find the common denominator
15 ÷ by 3 so you do the same to the numerator so, 48 ÷ 3 = 16
then keep the 22 and 16 and put it as 16/5 and 22/5 and add them to get 38/5
hope this helps
