Answer 1

Answer:

Capacity of glass = 25ml

Capacity of vessel = 4l 500ml

=4×1,000 + 500   = 4500ml (1l = 1,000ml)

No. of glass that can be filled = 4,500 ÷25 = 1804,500 ÷ 25 = 180

Therefore,

180 glasses can be filled by the vessel of curd.

To calculate estimate sum , first we'll round off the terms.

So, 5,290 rounded off to nearest 1000

→ 5000

17,986 rounded off to nearest 1000

→ 18000

5000+18000

= 23000

So, estimate 5,290+17,986 = 23,000.

463 estimated to the nearest ten = 460

182 estimated to the nearest ten = 180

∴ The required estimation = (460 + 180) = 640
