Answer: 112 7th graders ride the bus .
Step-by-step explanation:
Given: The proportion of 7th graders ride the bus to school= 35% = 0.35 [to remove % we divide number by 100]
If there are 320 seventh graders, then the number of 7th graders ride the bus = 320 x (proportion of 7th graders ride the bus to school)
Hence, 112 7th graders ride the bus .
A. yes. they form a proportion
1/4 and 6/24
6/24=1/4
1/4=.75
1/4=.75
First, convert into a decimal:
1/10,000,000 = 0.00000001
Next, convert to "the number with a power of 10 using a negative exponent. Move the decimal point to the first <em>number that is not 0</em> (sorry, there is a term for it, but i can't remember it right now, but it is not important to solving the answer)
0.000001 = 1 * 10^-7
1 * 10^-7 is your answer
