1) 4.725

2) 134,100

5)a) 180 degrees

5)b) 90 degrees

6) 2,776 people

7) 4.306

8) 7.80

9) 9835.48

10) 3814.52

14) Not bothering

15) twenty one thousand and four point five seven zero zero three

16) Divisible by 5

1.)4725./1000

When dividing by a number that starts with a 1 and has a buunch of zeros count the number of zeros and move the decimal to the left that many. So here, you have 1 with three zeros.

so 4725.0 /1000 = 4.725

2.)13.41X10,000

So multiplying is almost the same thing. You have a 1 with a bunch of zeros. Now you move the decimal to the RIGHT.

You have 10000 or a 1 with 4 zeros

so 13.41 x 10000 = 134100.

5.)a.)how many degrees are in a straight angle?

A straight angle is basically a straight line. The answer is 180 deg

b.)how many degress are in a right angle?

90 degrees, we also say its perpendicular. when drawing a right angle you may see a little square.

6.)Vans could hold 12 people. If they filled 231 vans. And have 4 people left over . How many people were there in all?

(231 x 12) +4

7.)31.433/7.3=4.30589

(you show the work now)

8.)179.3/23=7.79565

(you show the work now)

9.)9835.4813 round to hte nearest thousanths

so after the decimal place you have TENTHS, HUNDREDTHS, THOUSANDTHS, TEN THOUSANDTHS

so you want the THIRD digit right of the decimal place which is the 1

9835.481

10.)round 3814.5189 to teo deciaml places

when you dont have a TH, then you goto the left side of the decimal place. Here you dont. reading right to left ONES, TENS, HUNDREDS, THOUSANDS. so here you want the 1 in 3814

The answer is 3810.

14.)find the sum of the prime numbers that are between 12 and 48

Prime numbers cannot be divided by any number but 1.

Since you wanted the sum, you need to add them all up.

13 +17+19 +23 +29+ 31 +37+41 + 43 + 47

15.)use words to write the number 21004.57003

2 – TEN THOUSANDS

1 – THOUSANDS

0 – HUNDREDS

0 – TENS

4 – ONES

. AND

5 – TENTHS

7 – HUNDREDTHS

0 – THOUSANDTHS

0 – TEN THOUSANDTHS

3 – HUNDRED THOUSANDTHS

so, you have

twenty one thousand four AND five hundred seventy thousand three HUNDRED THOUSANDTHS

16.)is three thousand five divisible by 2,3,5, or 10?

If a number ends in 5, it can be divided by 5.

you would have to use a scientific cal for some of these unless your really good with doin’ it on paper.

can’t you use a calculator. Or figure it out on your own.
