Answers are:
16.
-1 - (-4) = 3
17.
-1-1/3 - (-4) = 2-2/3
18.
2 - (-1) = 3
19.
3-1/2 - (-1) = 4-1/2
20.
3-1/2 - 2 .= 1-1/2
21.
3-1/2 - (-1-1/3) = 4-5/6
Step by step: I took one point and subtracted the second point to get the length of each segment. You could also look at the ruler and count from one point to the other.
Remember when you subtract a negative, the two negatives become a positive
Answer:
#1- 7x*2=14x, the rest = 7x
Step-by-step explanation:
Percentages are really just fractions out of 100. So 45% is really just 45/100. If you want to find the lowest fractions, you have to break each number up into prime factors and see which overlap. So:
45 = 9x5
= 3 x 3 x 5
100 = 2 x 50
= 2 x 5 x 10
= 2 x 5 x 2 x 5
So 45/100 = 3x3x5/2x2x5x5
Now because there's a 5 on both sides, we can cancel down. If we do, that leaves us with
3x3/2x2x5
Which is 9/20
