The fifth-grade volleyball team has won 2/5 of its matches and the fourth-grade volleyball team has won 3/5 of its matches. If each team attended 20 matches, how many matches have they won altogether?

23 matches

Step-by-step explanation:

If the 5th grade team wins 2/5 matches, thats equal to 8/20, and 4th graders win 15/20, so together they win 23 matches out of 40

20

Step-by-step explanation: first you do 2/5 times 4 because 4 times 5 is 20

then you do 3/5 times 4 after that  once you have done 2*4=8 + 3*4=12

then 12+8=20.

wholesale price is the initial price before markup. retail price comes after the markup.

a price of 8 bucks that's marked up by 100%   is

formula: initial price + (percent markup in fraction/decimal)(initial price)

8+(1)(8)

8+8

16

retail price is $16.

4/6 = 2/3

so it should take 3/3 hours per man. so 9 hours is the answer 3*3 =9
