36 students have traveled outside of the United States, when there are total 120 sixth graders.

<u><em>Explanation</em></u>

The number of students traveled outside of the United States is 9 when there is total 30 sixth graders. So, the ratio of the student traveled to the total students will be 9: 30 = 3: 10

Now there are total of 120 sixth graders in the school and lets assume the number of students traveled outside the United states is x . That means the ratio...

x: 120 = 3:10 \\ \\ \frac{x}{120}=\frac{3}{10}  \\ \\ 10x=360\\ \\ x=\frac{360}{10} \\ \\ x= 36

So, 36 students have traveled outside of the United States.

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>

No, 4/10 is equal to 0.40 and not 0.45 since 4/10 goes in tens.
