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$20−4=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.

Complete the number sentence:

$48-\editable{}=19+16$48−=19+16

Complete the number sentence:

$15+39=9\times\editable{}$15+39=9×

Complete the number sentence:

$6\times\editable{}=24\div2$6×=24÷2
