In standard form what is (2 thousands 7 tens)÷10?

In standard form we have:

         2070÷10=207

The number in words is given by:

         (2 thousands 7 tens)÷10

Now, we know that:

2 thousands 7 tens is mathematically written as:  2070

( Because it means that 2 is written in thousand place,  7 is written in tens place)

Hence, we have to simplify the expression:

           2070÷10

( Now as we know both numerator and denominator have a common factor as: 10)

Hence, we cancel out 10 from numerator and denominator to get the result as follows:

                    2070÷10=207

e.

step-by-step explanation:

because there are always 10 numbers in a phone number.

it is a. 4.2 because 7.6-3.4 gets the remaining length of 4.2. i might be wrong but i am pretty sure this is the answer.
