Answer:

-2 and 21/50

Step-by-step explanation:

PEMDAS says that paranthases go first, so we solve 2 and 1/5 minus 33/12. 2 and 1/5 simplifies to the improper fraction, 11/5. Then we find a common denominater between 11/5 and 33/12 to get 60. 11/5=132/60, and 33/12=165/60. (132/60)-(165/60)=-33/60. Then we multipl that by 4 and 2/5, which can simplify to the improper fraction, 22/5. (22/5)*(-33/60) is -726/300, and simplifies to -2 and 21/50. Hope this helps!

Simon Whitfield Victoria, British Columbia, won the men's triathlon at the Sydney Olympics. The race consisted of 1.5 km swim in
Over [174]

Total triathlon distance →1.5 km + 40km  + 10 km = 51.5 km

So 51.5 km represents 100% of distance covered.

The % of each component = (distance of component/Total distance) multiplied by 100% so :

% of swim → (1.5 / 51.5) × 100 → 0.029 × 100 = 2.9%

% of bike ride → (40 / 51.5) × 100 →0.776 × 100 = 77.6%

% of  run → (10 / 51.5) × 100 → 0.194 × 100 = 19.4%

Percentage spent on land  will be

(40 km bike ride + 10 km run / Total triathlon distance) multiplied by 100%

(50 / 51.5) × 100 → 0.970 ×100 = 97%

Why is 6/8 greater than 5/8 but less than 7/8
My name is Ann [436]
Simple!

Since we can observe that they all have the same denominators (bottom part) we can just observe the numerator (top part)

6 is indeed greater than 5, yes? So we can safely say that

6/8 > 5/8

Now the for the second part. 

6 is smaller than 7, yes? So we can make the observation that

6/8 < 7/8

Hope that makes sense! (Be sure to thank me, plz)

P.S. If you want an example of unlike denominators, let me know. <span />
