**1) Nova school students are good players of Soccer. They won 16 games out of 20 played. Find the**

**percentage**

**of games won by Nova school students.**

Solution:

Total number of games = 20

Number of games won = 16

Fraction of games won = 16 out of 20 = 16/20

% of games won = 16/20* 100 = 1600/20 = 80%

Percentage of games won by Nova school students = 80

2) In a play school, 12 balls are red, 14 balls are green, 16 balls are white and 8 balls are blue. Find the percentage of i) Blue balls and ii) White balls

Solution:

Total number of balls = 12 + 14 + 16 + 8 = 50

i) Number of Blue balls = 8

Fraction of Blue balls = 8 out of 50 = 8/50

% of Blue balls = 8/50* 100 = 800/50 = 16%

Percentage of Blue balls = 16%

ii) Number of White balls = 16

Fraction of White balls = 16 out of 50 = 16/50

% of White balls = 16/50* 100 = 1600/50= 32%

Percentage of White balls = 32%

Solution:

Total number of games = 20

Number of games won = 16

Fraction of games won = 16 out of 20 = 16/20

% of games won = 16/20* 100 = 1600/20 = 80%

Percentage of games won by Nova school students = 80

2) In a play school, 12 balls are red, 14 balls are green, 16 balls are white and 8 balls are blue. Find the percentage of i) Blue balls and ii) White balls

Percentage of Blue balls = 16%

ii) Number of White balls = 16

Fraction of White balls = 16 out of 50 = 16/50

**3) Ronnie had 25 cookies and gave 36% of cookies to his friend Mark. Find the number of cookies Mark received.**

Solution:

Number of cookies = 25

Percentage of cookies given = 36%

Convert percentage into decimals by dividing 36 by 100

36% = 0.36

Number of cookies received by Mark

= 36% of 25

= 0.36 * 25

= 9

Mark can receive 9 cookies.

4) In a garden, 20% of trees are Guava, 35% of trees are Orange and rests of the trees are Mango.

If there are 500 trees in total, find the number of Mango trees.

Solution:

Total number of trees = 500

Percentage of Guava trees = 20%

Percentage of Orange trees = 35%

Percentage of Mango trees = 100% - 20% - 35% = 45%

Convert percentage into decimals by dividing 45 by 100

45% = 0.45

Number of Mango trees

= 45% of 500

= 0.45 * 500

= 225

There are 225 Mango trees.
