How you do this is you go from left to right with each one, and figure out which number is greater. For this particular problem the answer will be,
1.2 1.23 2.31 3.2
First of all, you must change 40% into a decimal by multiplying by 100⇒.40
Then you divide 55 by .40
55÷.40=137.5
Therefore, 55 is 40% of 137.5
It depends on what course you are taking mainly tis just 2 years but if your taking a bigger course it could be up to 6 years.
A. 20 children and 10 adults
Equation 1: a + c = 30
Equation 2: 8a + c = 100
B. 10 children and 20 adults
Equation 1: a + c = 30
Equation 2: 8a – c = 100
C. 10 children and 20 adults
Equation 1: a + c = 30
Equation 2: 8a + c = 100
D. 20 children and 10 adults
Equation 1: a + c = 30
Equation 2: 8a – c = 100
hope it helped
