Last year the backgammon club had 30 members. This year the club had 24 members. Find the percent of decrease in the number of m
Gnom [1K]

There is 20% decrease in the number of members.

Step-by-step explanation:

Given,

Members last year = Old value = 30

Members this year = New year = 24

Change = New value - Old value

Change = 24 - 30

Change = -6

The negative sign indicates the decrease.

Decrease percent = \frac{Change}{Old\ value}*100

Decrease percent = \frac{6}{30}*100

Decrease percent = \frac{600}{30}

Decrease percent = 20%

There is 20% decrease in the number of members.

Rewrite 5/ 16 + 6/ 20 with a common denominator.
Troyanec [42]
25/80 + 24/80 = 49/80. 16 and 20 both go into 80. !6 goes in 5 times so you multiply 5 by 5. 20 goes into 80 4 times so you multiply 4 by 4. 24/80 + 25/80 = 49/80.
