170 Arrow-Puffin-3_Semester-1 Maths%u2022 Division on a number lineWe can divide 15 pencils equally among 3 children using a number line.15 3 = 5Start at 15. Move 3 steps backwards at a time on the line. You reach 12.0 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 205 4 3 2 1From 12 again move 3 steps backwards at a time. You reach 9 and finally you reach 0. How many times do you move to reach 0?Clearly you move backwards five times. Hence 15 %u00f7 3 = 5Divide by repeated subtraction.1. Mother has 18 chocolates. Divide them equally among 3 children.2. Mina has 12 balloons. She gives them to 4 of her friends. How many does each get?Divide on the number line.1. 16 4 = 2. 28 7 = 3. 24 3 = 5 %u2013 5 = 0 (No more pencils left)We can subtract 5 from 15, 3 times. So, when 15 pencils are distributed among 5 students each child gets 3 pencils.Therefore, 15 %u00f7 5 = 3<<<<< Let's Practise 5.2 Application Let's Practise 5.3 ApplicationLet's Understand Conceptual Understanding
