Scilla [17]

Alright so the answer would be letter B, because

win-to-loss

49 to 21 (You can determine her losses by subtracted the number of wins from her total number of games played)

Now you must simplify your answer

7 is the greatest common factor (GCF) of both 49 and 21

Now divide both 49 and 21 by 7 to get

7 to 3

Juanita runs every third day and swims every fifth day. If Juanita runs and swims today, in how many days will she run and swim
Ber [7]

we know that

The least
common multiple (LCM) of two or more numbers is the least

number, other than zero, that is a multiple of all the numbers.

In this problem, we are looking for the least common multiple of 3 and 5

So

Multiply 3 by 5

LCM=3*5\\ LCM=15

therefore

On the 15th day after today, she will do both on the same day

the answer is

15 days
