    50% is our friend because it tells you that it's half of whatever number you have and it tells you if the number is greater or less then the number you have. It is beneficial because it is a easy landmark to memorize and it tells you thats it's half of whatever number you have.<3 :)

    Fifty percent is your friend because all you have to do to find fifty percent of a number, you just need to divide it by two.
    It's benificial to know the landmark fifty percent because you can get a good estimate if it's is greater or less than fifty percent. For example: if you have 9/22, you can divide twenty-two by two and get eleven. Then, you can compare and see that nine is less than eleven; therefore, nine is less than fifty percent of twenty-two.

    50% is your friend because you can use it to help you figure out the fraction or decimal. Like you said 9/10 times on a state test if you know 50% you don't need to use pencil and paper.

    It is your friend because it is a landmark. It helps you by telling you if another fraction is bigger or smaller than half.

    50% is your friend because it helps you tell if your fraction could divide in half. It is beneficial because it is a landmark and it helps you by telling if your fraction is more or less.

    50% is your friend because if you don't have a numerator that is half of the other denominator, you see what is half of the denominator and see if the numerator is more than 50% or less than 50%.

    50 % is your friend because to find 50 % all you have to do is divide it by 2. For example: how we did 2day, 4/8, 32/64, 82/163, 16/32: which one is not friendly well the answer is 82/163 because all of the other ones are 50% but 82/163 is NOT 50% half of 163 is 81 1/2 and double the 82 is 164.

    50 percent is your friend because 50 is a land mark. the reason it is a land mark because it is easy to find. half is easy to go by if you want to find a percent like 60. if you now 50 it is easy to find 60 percent.

    50% is your friend because it is a landmark. It is also your friend because it tells you weather you need to lower the numerator or rise it.
    If the numerator is doubled and equals the denominator it is 50%. Ex. 1/2, 50/100, 14/34. Hint: it is easier if you find the denominators, it is also better if you simplify the fraction first. 1+1=2 so 1/2 is safe. 50/100 is the same as 1/2 and 1/2 is safe. 23+23=46. 14+14=28. 28 is lower than 34 so the real answer would be at least lower than 50%.

    50% is your firend because for you to find 50% you have to divide the number by 2. And if your top number is not equal 50% you find out if it more or less than 50% .

  16. 50% is your friend because it is easy to divide and you can tell if the fraction is higher, lower, of half of it. 50% is equal to 1/2 which is a landmark.

    50% should be your friend because 50% helps you estimate without even having to work it out the problem on a piece of paper. It would be beneficial to know 50% as a landmark so it would help you estimate your answer and check for reasoning.
