Answer 1

Most of these are solved by dividing the amount by the time period.

Example: $945 / 6 weeks = $157.50 / week

243 Miles / 9 hours = 27 miles/hour

Unless you need to show long division, this would should be sufficient.

Answer 2

1. 243/9=27miles/hour
2. 945/6=$157.50/week
3. 24+38=62
so the ratio is $38 to $62; $38/$62; $38:$62 those are the three ways to show ratios
4. A different answer look at it but jesse gets paid more
5. 6/24 =.25 or 25%
6. 9100/.28=32,500
7. x*1.25=9.5
x=9.5/1.25
x=7.6
she made $7.60/hour
check ya later ♥

Answer 3

1.) (Jenny) 243/9=27 miles per hour

2.) (Bobby) $945/6=$157.50 per week

3.) (Friday night) $38 + $24 =$62
38/32=61% on dinner
24/62=39% on movies

4.) (Sharon) $739.8/42=$17.61 per hour
$737.17/39=$18.90 per hour
No, they do not make the same hourly rate.

5.) (Claire) 24/6=4
100/4=25
So, 25% are red.

6.) (Shannon) 9,100=28%
100/28=3.57
3.57x9,100=32,487
She made $32,487 last year.

7.) (Regina) $9.50/1.25=7.5
She earned $7.50 per hour last year.


*You really should be doing your homework yourself. You never know how many people are giving youthe wrong answers.

Answer 4

1) 243/9 = 27 mph
2) 945/6 = $157.50
3) 38/62 = 61%

Answer 5

for the jenny one...
you divide 243 by 9 to find out the rate, which is how many miles she drove each hour. to show your work you could do 243 over 9 =...and then whatever the answer.

Answer 6

i will answer your first question ( i just finished algebra homework so i cannot do any more math than that!!) 243 miles in 9 hrs equals 27 mph, 27*9=243. if you drive 27 mph for 9 hrs you will travel that many miles....simply divide the miles by the hours and you get miles per hour...good luck!!

Answer 7

a million. 504 miles. 2. 855 pupils won't graduate. 3. in one month, $4.50 is further to the 300 4. comparable as a million, your call question. 5. $4.86 cents rounded. 6. 2/6,3/9,4/12,5/15 are most of the various equivalent ratios of a million/3

Answer 8

rate of speed is in miles per hour, which means miles/hours

weekly salary means dollars per week, or $/weeks

you can calculate the remaining ratios in a similar fashion
