Question

2. When subtracting, 4 tens will be regrouped into
tens and
ones.
a. I, 3
b. 3, 2
c. 3, 10
​

Answer 1

Answer:

if you regroup the tens: (take one ten, break it to 10 ones)

5 tens - 1 ten = 4 tens

then put all the ones into the ones column

9 ones + 10 ones, (from the broken up 10) = 19 ones

Therefore : 4tens and 19ones regroups to/from 59

hope this helped!

Answer 2

4 tens will be grouped as 3 tens and 10 tens.

GIVEN

subtraction for 4 tens.

TO FIND

Grouping of 4 tens.

SOLUTION

We can simply solve the above problem as follows-

It is given that,

4 is in tens place

Let us assume that The number is 40

Let 40 be subtracted by 7

We know that 0 is in ones place will be substrates from 7 ones,

As the 7 cannot by subtracted by 0,

One tens will be borrowed by 4 tens to make 10 ones to easily subtract 7 from 10 to get 33 as a result.

So, 4 tens will be grouped as 3 tens and 10 tens.
