What percentage of students age 15 and above travel to school by bus? Round to the nearest whole percent. Can someone please work it out step by step thank you!

Students 15 & above by car = 98-18=80
Students 15& above by bus = 195-(80+65) = 50
% of students 15& above by bus = (50/195) x 100 = 25.6410%
Rounding off, 26%

The decimal expansion would be .27 repeated

First step is to get rid of the square root. remember that a square root is the same as raising to the (1/2) power. see below: multiply exponents per exponent rules to get: remember you subtract exponents from the denominator and add exponents in the numerator so: simplify further: so a is the correct choice. if you don't understand this google exponent rules and it will you understand. look at the image results.
