Answer 2

Answer:

Answer Type

Question 1.

Find the ratio of 75 cm to 1.5 m.

Solution:

The given numbers are not in the same units. So, converting them into same units.

1.5 m = 1.5 x 100 cm = 150 cm

[∵ 1 m = 100 cm]

∴ The required ratio is 75 cm : 150 cm.



∴ Required ratio = 1 : 2

Question 2.

Give two equivalent ratios of 3 : 5.

Solution:



Thus, 9 : 15 and 6 : 10 are the two equivalent ratios of 3 : 5.

Question 3.

Fill in the blank box.



Solution:



Question 4.

Check whether the given ratios are equivalent or not. 27, 621

Solution:



∴ They are equivalent ratios.

Question 5.

Divide 60 in the ratio of 2 : 3.

Solution:

Sum = 2 + 3 = 5

∴ First part = 25 x 60 =24 5

∴ Second part = 35 x 60 =36 5

Thus, the required two parts = 24 and 36.

Question 1.

Represent the following on number line:

(a) -5
