Pls help I can't do anything I will give the brain thingy
Sidana [21]

Step-by-step explanation:

<u>Blank</u><u> </u><u>C</u> :

Given total = 68

No. of TV news = 13

Therefore, in Internet it would be = Total - TV news

= 68 - 13 = <u>55 (ans)</u>

<u>Blank</u><u> </u><u>D</u> :

No. of Internet news in 7th grade = 55

No. of Internet news in 8th grade = 64

Hence, total Internet base news = 64 + 55 = <u>119 (ans)</u>

<u>Blank</u><u> </u><u>B</u> :

All total = 138

Internet news total = 119

Hence, TV news total = All total - Internet news

= 138 - 119 = <u>19 (ans)</u>

<u>Blank</u><u> </u><u>A</u> :

No. of TV news in 7th grade = 13

Total news in TV = 19

Therefore, no. of TV news in 8th grade = 19 - 13 = <u>6(ans)</u>

<u>Blank</u><u> </u><u>E</u> :

All total = 138

Total of 7th grade news = 68

Hence, total of 8th grade news = 138 - 68

= <u>70 (ans)</u>

In a recent year, 22 percent of email users said they spend less time using email because of spam. what fraction of email users
Alchen [17]
Remember, percent is always out of 100. If you have 22%, you have 22 people per every 100 people, or, 22/100. 

22/100 is the incomplete answer because it needs to be simplified. If you divide both numbers by two you get 11/50 which is the lowest fraction you can have because 11 is a prime number.
