1) C
2) I don't understand the question<span />
Its equivalent percent is less than 100% and its equivalent decimal is less than 0.99 or less.
For example, 1/2 is a fraction between 0 and 1. Its percentage is 50%, which is less than 100%. Its decimal is 0.50, which is less than 1 or 0.99
You have to do plus for all like this 72+6+54×60 =3318 this is my answer and I hope is right.
A perfect square is a number which contains a a factor that involves a number multiplied by itself. You could also say a perfect square, when taken the square root of such a number, involves a whole number answer. Either explanation would work, and there are surely mainly more haha. 25 is the perfect square because 5×5 is a factor of 25, while 50 doesn't have a factor of the same numbers.
A = 3 and b is 2 so 3 + 2 = 5
a - b = 1
Therefore : 5/1
