3 Fill in the missing numbers. Let’s try b) 772 = 300 + ______ +30 + 40 +2 • On the right side of the equation, you know there are 700, 70 and 2. • On the other side of the equation, 300 hundred is already given. How many hundreds are left? 700-300 = 400 • Now look at 72. On the right side of the equation, check if 30 + 40 + 2 = 72. Yes. The equation is balanced. • So what is the missing link? Do you have another way of working this out? Let’s try another one: c) 859 = 250 + 550 + 40 + 10 + _______ What are the ways you could solve this question? • How many hundreds in 859? • On the other side of the equation, how many hundreds are there? • How many tens? • How many ones? • What is missing? Do you have another way of working this out?
