Can 31/50 be simplified

Answers

no because when one number is odd and the other one is even it can't be simplified (unless they are multiples/factors of each other) ex: 7/14

No, 31, a prime number, can not be divided any more to become another numerator, not to mention having to correspond with 50 as well.

Mr Elvis divided his money in the ratio 2:6 between Eric and Shan Eric got the smaller amount of 240 dollars. how much did Shan get?

Answers

He divided his money in a 2:6 ratio and Eric got the smaller amount.
First you have to add 2+6 and you get 8
so the total is 8
Next find out what fraction is 2 over 8
2/8=1/4
so, 1/4 is $240
so now take away 1/4 from 4/4 and you get 3/4
To find how much money Shane got you multiply the quantity given by the reciprocal of the fraction---------- 240/1*4/1
Your answer is $960
So 3/4 or Shane's amount is $960

there are 750 people at a football game. Out of this number, 320 are students. What percent of the people at the football game are not students? Round to the nearest tenth if needed?

Answers

to do this problem you use is/of=percent/100
So:
320/750=x/100
cross multiply
32,000=750x
divide both sides by 750
x=42.66 repeating

ANSWER: X=42.66 REPEATING

You need to use this equation:
part of the whole = percentage x whole (simpler, it is a=pw)
In this case, it would be
320 = p x 750
Because p is the percentage we are trying to find.
You would then divide both sides by 750 to isolate p.
320 divided by 750 is 0.4266, and rounding to the nearest tenth it would be 0.43. Now your equation is
0.43 = p
To make it a percentage you move the decimal to the right two times. That makes your equation
43 =p
So 43% of the people at the football game are not students.
