He started with 16 because he sold half so add half and that would be 16 ;)
Answer:
4/10 = 2/5
Step-by-step explanation:
It's asking you what's an equivalent fraction to 4/10. 4/10 is equivalent to 2/5 because the size of 2 parts out of 5 is the same size as 4 parts out of 10.
Draw out a number line with the values 0, 5, 10, 15, 20, 25, 30, etc (basically multiples of 5)
Then plot a point at 25
-----------------
Or you can draw out a number line with the multiples of 10, so with the values 0, 10, 20, 30, ...
Then plot a point at the exact midway point between 20 and 30 to represent the value 25
Answer: See below.
The sine ratio is the ratio of the opposite side over the hypotenuse in a right triangle. The hypotenuse is always the largest side of a triangle.
Therefore, the denominator will always be the largest. If the denominator is larger than the numerator, it will be a number less than one.
And it will be positive because it is an acute angle so the triangle when plotting in the unit circle would only be in the first quadrant. All values in the first quadrant are positive.
