ok I have a couple more questions:
multiplying fractions, is this correct?:
2/9 x 5/7= 10/63?
7/8 x (-2 5/14)= 2 -7/112?
7t/16 x 10/15= 35t/120?
Now adding fractions:
2n/9 - -n/4= 17n/36?
2 3/10- 7 3/20= -4 17/20?
Now putting fractions into decimals:
72/125= 0.576 13/11= 1.18 (18 is repeating)
Now ordering fractions from least to greatest:
-3/4, -1/2, -2/3, -4/5
-45/60 -30/60 -40/60 -48/60
new order: -1/2, -2/3, -3/4, -4/5??
-1/4, -1/8, -0.75, -0.625
-0.25 -0.125 -0.75 -0.625= -0.75, -0.625, -0.125, -0.25?
