First set up a proportion.
14/210 = x/27900
then divide 27900 by 210 which equals about 133
then multiply 14 by 133 which is 1862
your answer is 1862
60% is the answer
I hope you have a good day :)
Answer:
16.66
Step-by-step explanation:
1) eliminate constant first by performing the opposite operation:
0.24a+0.5-0.5=4.5-0.5
0.24a=4.0
divide both sides by 0.24
a=16.66
10 times the sum of 2 and 1 is represented by the following expression:
10 x (2 + 1)
10 x is ten times, and (2 + 1) the sum of 2 and 1, "10 times the sum of 2 and 1".
