Balancing with mixed operations I
Lesson

In Balancing Numbers up to 50 we saw that number sentences are balanced if both sides of the number sentence have the same value.

Example: $20-4=13+3$204=13+3

In this number sentence both the left and right sides of the sentence are equal to $16$16.  So we say the number sentence is balanced.

Look at this video to see how to solve maths problems involving balancing number sentences.

#### Worked Examples

##### Question 1

Complete the number sentence:

1. $48-\editable{}=19+16$48=19+16

##### Question 2

Complete the number sentence:

1. $15+39=9\times\editable{}$15+39=9×

##### Question 3

Complete the number sentence:

1. $6\times\editable{}=24\div2$6×=24÷​2

### Outcomes

#### NA3-1
