"B. The English Channel helped protect the island nation of Britain from invasion" would be the best option from the list, since this Channel was oftentimes very choppy with strong currents.
You can do this using fractions. Start with 10 over 5-
10 mangoes 18 mangoes
------------------ = --------------------
5 minutes x
we put x there because that is the part of the equation we need to find out. You can do this in a couple of ways. One way is to multiply 18 by 5, and divide by 10.
18×5= 90, and 90 is divisible by 10. 90÷10=9. 9 is your answer.
There are multiple strategies, so here is another way to solve the problem. This is probably the simplest way, but it doesn't work with some
We are using fractions again, so here is what we start with:
10 mangoes 18 mangoes
------------------ = -------------------
5 minutes x
Now, you can just divide the fraction(numerator divided by denominator). For normal fractions, like 1/4 or 5/8, the answer would be the decimal version of the fraction. However, we are using improper fractions, so the answer will be greater than one.
10÷5=2, so if you divide 18 by 2, you get 9, confirming the answer we got with the other strategy.(There is one more strategy, but it takes a little longer to do.)
Hope this helped! Sorry if it's long.
I can for you!!!
Plsssdssd
Dont know sorry
have a nice day
