Answer:
382 - 33 = 349
382- 44 = 338
382 - 35 = 347
Step-by-step explanation:
First let's see what ungroup is.
We are given a number 382
If ungroup this number, we get 3 hundreds 8 tens and 2 ones.
This is called ungrouped.
We are asked to write the subtraction equation in which only tens is ungrouped.
So we need to use the number 382 where only tens place should be ungrouped.
Here the tens place value digit is 8, it means there are 8 tens.(8 *10 = 80)
So we need to subtract a number such that tens should be ungrouped in 382.
The number that should have one's place should be greater that 2, then only we can ungroup tens in the number 382.
We can have many such numbers, 33, 34. 35. 36. 39, 43, 44, 45 and so on.
We can use any of those numbers subtract from 382 in which only tens is ungrouped.
382 - 33 = 349
In 33, the ones place is 3 and in 382 ones place is 2. We cannot subtract 3 from 2.
So we ungroup tens, there 8 tens, we take 1 tens and brake into 10 ones.
Now we will have (10 +2 = 12 ones) from 12 ones we subtract 3 ones, so we get 9 on the ones place.
Similarly, we can write many subtraction equation using the number 382 in which only tens is ungrouped.
382- 44 = 338
382 - 35 = 347
and so on.
