Arrow-Puffin-4_Semester-1 Maths 159 Do the following story problems.1) 270 balloons are distributed equally so that each child gets 3 balloons. Find out the number of children who get them.2) A metro train carries 459 passengers in all its 9 coaches. How many passengers are there in each coach?ESTIMATION OF QUOTIENTTo find the estimated quotient, we first round off the dividend and divisor and then we find the quotient.Example 1 : Find the estimated quotient of 7,452 %u00f7 54.Estimate the quotient by rounding off the dividend to the nearest thousands and the divisor to the nearest tens.Estimated quotient = 7,000 %u00f7 50 = 140Actual quotient = 7,452 %u00f7 54 = 138Example 2 :A company needs to mail 1104 cheques to the bank. If they put 24 cheques in each envelope, how many envelopes do they need?Estimated cheques the company needs to mail = 1,000Estimated cheques in each envelope = 20Estimated envelopes the company needs = 1,000 %u00f7 20 = 50Actual envelopes the company needs = 1,104 %u00f7 24 = 46 Find the estimated quotient.a) 2675 %u00f7 27 b) 4446 %u00f7 57 c) 5981 %u00f7 72 d) 9872 %u00f7 73e) 5981 %u00f7 72 f) 4862 %u00f7 12 g) 5846 %u00f7 57 Let's Practise 4.13 ApplicationLet's Understand Conceptual UnderstandingMaths in Real Life Case Study Based Questions
