Answer:

1. 20

2. 20

3. 50

4. 40

5. 80

6. 70

Step-by-step explanation:

When you round, in this case to the tens place, you look at the number to the right of the value given. So if we are asked to round to the tens place, we must actually look at the ones place.

<h2><u>Remeber:</u></h2><h2><u></u></h2><h2><u>0 - 4 = round down</u></h2><h2><u></u></h2><h2><u>5 - 9 = round up</u></h2><h2><u></u></h2>

1. 2<u>4</u>

=> 20

2. 1<u>5</u>

==> 20

3. 4<u>7</u>

==> 50

4. 4<u>2</u>

==> 40

5. 8<u>1</u>

==> 80

6. 6<u>5</u>

Ksenya-84 [330]

Answer:

"6 out of 10 people" means the ratio of class:no_class is 6:4

990/10 = 99, the smallest the "class" and the "no_class" add up to is 10. And, generally, the total divides with that nicely, as in this case.

99(6) = 594 ----------- probably class

99(4) = 396 ------------------ probably no class

Total  = 990
