can someone please try to help im not good with proportions
Well, if he worked 18 hours, and got payed 92 dollars, how much did he get payed per hour?
The question is how much did he make per hour.... per means to divide so word for word make per hour means 92 / 18 That would give you 5.11 per hour. so how many $5.11 are there in $138 138/5.11 27.0058 hours I would assume you would answer 27 hours.
ok yea that makes sense so just break it down step by step
how do i find a proportion for x like this x/6 = 6/4
but its like x is above the 6 and the 6 is above the 4 i guess like cross multiply
Whenever you have a fraction = a fraction you can always cross multiply (top left times bottom right = bottom left times top right) x 6 - = - 6 4 so x times 4 = 6 times 6 4x = 36 x = 9
wow thank u i should of typed it like that lol ok so 4x = 36 and x = 9 but is that the answer ?
Yes.. you are wanting to know what x equals and x = 9
ok so i should only get one answer which is x
In other words 9 6 - = - 6 4 if you reduce both of those fractions you get 3 - 2
ok can u please tell me how to reduce do u just find the factors that go into each numbers
ok im confused im trying to do 9.5/19 and x/30
please can someone help
i did 9.5 times 30 and got 285 but now im stuck
9.5 x --- = --- 19 30 30(9.5) = 19x 285 = 19x x = 15
oh so i do 30 times 9.5 ok sorry i did the oposite
It doesn't matter which way you multiply, you get the same answer.
oh ok yea because i did get 285
At a certain time of day, a tree casts a 9-foot shadow at the same time that a person 6 feet tall casts a 4-foot shadow. What is the height of the tree?
shadow / height = shadow / height
9 divided by 6 = 1.5 correct
9 6 - = - x 4 9(4) = 6x 36 = 6x 6 = x
i had to cross mutiply
WAIT I WAS WRONG.
9 4 - = - x 6 9(6) = 4x 54 = 4x 16 = x
Shadow of tree Shadow of person ------------ = -------------- Height of tree Height of person
ok i understand now so that would mean the answer is 16=x
OR You can do Shadow of tree Height of tree ------------- = ------------ Shadow of person Height of person 9 x - = - 4 6 9(6) = 4x 54 = 4x x = 13.5
I am SO sorry... don't know what is wrong with my math. They both = 13.5 because 54/4 = 13.5 (I don't know WHERE I got 16)
its ok really everyone makes masteakes
ok so the answer is 13.5
:) thank you wonderful
U R Welcome
im going to try the next one if i get stuck ill get back to to
x/27 = 4/9 i did x times 9 and i got 9x the i did 9x times 9x and got 81 is that correct
am i correct blexting
