Question

Write a number sentence to add 6 ones to 21

Answer 1

6 + 21 = 27 (Add six ones)
60 + 21 = 81 (Add six tens)

Answer 2

The required number sentence is 6 + 21 = 27.

Explanation:

We are required,

To write a number statement in order to add 6 ones to 21.

Now as we know,

'Ones' refer to the unit number 1.

Then '6 ones' means that the number is 6×1 = 6

Thus, we get that,

The sum of '6 ones and 21' is 6 + 21 = 27.

Hence, the required number sentence is 6 + 21 = 27.
