Answer 1

Answer:

What will be one fifth of the length of longest wingspan?

Answer 2

Answer:

I. (c) Blue jay

ll. (a) 1/2 m

lll. (d) none of these

IV. (a) 25:36

V. (d) 4/5m

Given:

Wingspan of various species of birds:

Blue jay = 41/100 m

Golden eagle = 2 1/5 m

Sea gull = 1 7/10 m

Albatross = 3 3/5 m

To find:

I. Which bird has the smallest wingspan?

II. What will be one fifth of the length of wingspan of Golden eagle?

III. What is the one hundredth of the length of the wings span of the bird that has longest wing span?

IV. The ratio of the wingspan of golden eagle to the wing span of Albatross is?

V. The difference of the length of the wingspan of Golden eagle and sea Gull is?

Solution:

l. Bird with smallest wingspan is Blue jay

ll. 1/5th of the length of wingspan of Golden eagle

= 2 2/5 ÷ 5 = 0.5 or 1/2

lll. 1/100th the length of the wings span of the bird that has longest wing span = 2 2/5 ÷ 100 = 0.025

lV. The ratio of the wingspan of golden eagle to the wing span of Albatross is 2.5 : 3.6

= 25:36 (by multiplying with 10)

V.The difference of the length of the wingspan of Golden eagle and sea Gull is 2.5 - 1.7

= 0.8 = 4/5
