Manuel is riding on a bike course that is 90 miles long. So far, he has ridden miles of the course. What percentage of the course has Manuel ridden 54 miles of the course . what precentage of the course has manuel ridden so far

60% of the course

Step-by-step explanation:

54 equals ? of 90

54/90 = 0.6

0.6 = 60%

Manuel has ridden 60% of the course.

the largest number of the four options is 1.8 x 10-2

you have it in scientific notation.

1.80 x 10-6   = 0.00000180

1.80 x 10-4   = 0.000180 (bigger, or "less small", than the former one)

so

1.8 x 10-2       = 0.0180. as you see. the "less small", or the biggest one of them all.

as you have negative exponent, it means you are dividing 1.8 by 100 (i.e. moving the dot towards left, two times).

if you had positive exponent for the scientific notation, power of tenths, you would be multiplying times 100 (moving the dot towards right) as below:

1.8 x (10)2 = 180

so. if you have negative exponent in scientific notation, move the dot toward left. if it is positive, toward right as many times the exponent tells you.
