Use PEMDAS.
1. multiply the 7 and the 4 by 3
2. square the 12 to get 144
3.multiply 144 by -14
4. divide -2016 by 7
5.subtract 288 from 21 (if you subtract 21 from 288 you get 267 so put +- in front for both answers :) )

What simplified ratio correctly compares 27 feet to 36 feet?
Kobotan [32]

The simplified ratio that correctly compares 27 feet to 36 feet is 3:4

Step 1: Simplify the ratio by finding common factor

Step 2: Here, in this case the lowest common factor is 3. Divide both numerator and denominator by 3.

The city park is 9 and 2/5 km from Roland Public School. The city library is 3 and 3/10 km from the same school. How much farthe
Marina86 [1]

Answer:

6 1/10

Step-by-step explanation:

Convert the mixed numbers into improper fractions (denominator × whole number + numerator / denominator):

9 2/5 = 47/5

3 3/10 = 33/10

Convert improper fractions to have the same denominator:

47/5 × 2/2 = 94/10

Find the difference by subtracting the numerators:

94/10 - 33/10 = 61/10

Convert the answer into a mixed number:

61/10 = 6 1/10
