Answer:
6/25 x 3/4 = 18/100 % 16/5 = 18/100 x 5/16 = 90/1600 or 0.05625
Can also be simplified to 9/160
No not rational because you cant divide it
Answer:
2
Step-by-step explanation:
68+48=116
116÷16=7.24 (wrong)
116÷12=9.7 (wrong)
116÷4=29 (lowest even)
116÷2=58 (highest even)
If I'm wrong, let me know
1. 81 1/2 = 163/2
2. 32 1/5 - 64 1/3 =
483/15 - 965/15 =
-482/15 or -32 2/15
3. 16 1/4 = 65/4
4. 49 1/2 + 27 1/3 =
99/2 + 82/3 =
297/6 + 164/6 =
461/6 or 76 5/6
Use Pythagorean theorem:
9i-j = sqrt (9^2 - 1^2) = sqrt(81-1) = sqrt80
now divide both terms in V by that:
u = 9/sqrt(80)i - 1/sqrt(80)j
