Answer:

1.A. 88.89

2.B.6.3%

3.C.64.92%

Step-by-step explanation:

1.\frac{8}{9}=0.8888

to covert it into percentage multiply it with 100

then it becomes 88.888

rounding off to the nearest hundred it becomes 88.89

2. to convert into percentage multiply it with 100

therefore 0.063×100=6.3%

3. to find percentage

    %= (no of students using mobile / total no of students )× 100

       = \frac{792}{1200}×100

       =64.918

Rounding off to nearest hundred it becomes 64.92%

Answer:

1) A. 88.89%

2) B. 6.3%

3) C. 64.92%

Step-by-step explanation:

1) After dividing 8 by 9, we get, \frac{8}{9} = 0.8889.

Now, percent of \frac{8}{9} = 0.8889 * 100 = 88.89%

Hence, percent to nearest hundredth is 88.89%

2) We want 0.063 to be written in percent form

i.e. 0.063 * 100 = 6.3%

Hence, 0.063 into percent form is 6.3%

3) We are given that the total number of students are 1220 and the number of students that have cell phones are 792.

Therefore, the percent of students having cell phones = \frac{792}{1220} *100 = 64.92%

Hence, the percent of students having cell phones to nearest hundereth is 64.92%
