at southeast middle school 16 1/4 % of the students wear braces. what fraction of the students wear braces?

Hey there!

16 1 / 4% = 16(4) + 1 = 64 + 1 = 65

65 / 4% = 16.25%

• Percentages usually run out of 100

16.25 / 100

• Finding out the ratio of your given number, multiply the numerator and denominator by the number 4

16.25 * 4 / 100 * 4

16.25 * 4 = 65 (numerator)

100 * 4 = 400 (denominator)

• Equation: 65 / 400

• REDUCE the GIVEN FRACTION (65/400)

• Once when you have the fraction reduced you should have came up with: 13/80 (aka your answer)

• 13/80 ☑️

Good luck on your assignment and enjoy your day!

the answer is 0.3175 hope that you ^w^

also you might actually want to put this picture up if you want people to solve it luckily i remember this question

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.
