Answer 1

Answer:

a)4:10

b)6:4

c)6:10

Step-by-step explanation:

a)no. of blue pencil=100-60

=40

no. of total pencil=100

Ratio=40/100

4:10

b)no. of red pencil=60

no. of blue pencil=40

ratio=60/40

=6:4

c)no. of red pencil=60

no. of total pencil=100

ratio=60/100

=6:10

Answer 2

(a) total no of pencils = 100

100-60=40

therefore blue pencils = 40

the ratio of blue to the no of pencils

=40:100

2:5

(b)= 60:40

=3:2

(c) =60:100

=3:5
