Question

COMPARING quantities Class 7 ​

Answer 1

Answer:

See below-

Step-by-step explanation:

1- (a) 12/16 x 100= 75%

(b) 3.5 x 100= 350%

(b) 49/50 x 100= 98%

2- Absent% = Absent/total x 100

= 8/32 x 100= 25%

3- (a) 1:4

1st part= 1/4+1 x 100 = 1/5 x 100= 20%

2nd part= 4/4+1 x 100= 4/5 x 100= 80%

(b) 1:2:5

1st part= 1/1+2+5 x 100= 1/8 x100= 12.5%

2nd part= 2/8 x 100= 25%

3rd part= 5/8 x100= 62.5%

4- 16/25 x 100= 64%

5- total % = 100%

male% + female% + children% =100%

children%= 100%-30%-40%= 30%

6- matches won= 25% of 20= 25/100x20= 5matches
