Answer 1

Answer:

1) 4:15

2) 3:100

Step-by-step explanation:

(i)

We know that 1 m = 100 cm.

Then, 1.5 m = 1.5 * 100

                   = 150 cm.

Ratio of 40 cm to 1.5 m = (40/150)

                                       = 4/15

                                       = 4:15

(2)

We know that 1 cm = 10 mm.

Then, 20 cm = 200 mm.

Given that Length of pencil is 20 cm and diameter is 6 mm.

Ratio of Diameter of pencil to that of its length = 6/200

                                                                              = 3:100.

Hope it helps!

Answer 2

Step-by-step explanation:

(1)

4 cm to 1.5 m

4 * (1.5 * 100)

4 * 15

Ratio = 4/15.

(2)

Length = 20 cm.

Diameter = 6 mm

                = 0.6 cm.

Ratio = 0.6/20

         = 6/200

         = 3:100
