Answer:
rs6657
Step-by-step explanation:
I'm not going to do all of them for you but I'm basically going to teach you what your teacher taught you.
In division with fractions, the second fraction will be flipped around and then you'll multiply normally.
Example:
(5/3)/(2/3)
You would flip around the 2/3 so it would be 3/2
Then you would multiply:
5/3*3/2
To do multiplication, multiply the top numerator by the top numerator and the bottom numerator by the bottom numerator as I'm sure you've already learned
5*3 = 15
3*2 = 6
15/6
Let me know if you have any questions
If you're wondering why I didn't give you the answer, it's because "Give a man a fish and he'll eat for a day; teach a man to fish and he will eat for a lifetime"
Thank you
Answer would be 110 because if a figure has 4 angles all it's angle lengths add up to 360°, so since one of the angles is 70° and there is another angle that's identical to it, 70+70= 140, so you have to do 360-140 which gives you 220, and 220/2 = 110°
ok so 10 pennis is 1 dime which is 10 cents ok lets go to the next number 20 pennis will be 2 dimes because its the same cents then 30 pennis will be 3 and 40 will be 4 so just divide 10 into the number of pennis or in this case you have a easy out you can just use the numbers infront of the zero since you are talking about dimes.
It would even be the same if you had 2,300 pennis you would have 230 dimes
So, there are 48 states, let's divide them into 16 groups (because 7+9=16)
48/16=3
so that means there are 16 groups of 3 states.
and those groups are in a ratio of 7:9, seven to 9 groups.
I assume that the 7 refers to the states that border an ocean, then the number of states will be 7*3=21
