If 45.78 ÷ 1.7 is written in long division form as long division set up where 17 is on the outside of the division symbol and 45780 is on the inside so that the divisor is written as a whole number, where should the decimal point be placed in the dividend?

Answer:

The dividend will be 457.80 and divisor will be 17.

Explanation:

The divisor is 1.7

The dividend is 45.78

We want 17 that is on the outside of the division symbol, written as a whole number.

45780 is on the inside of the division symbol.

So, to make 17 whole number, we will multiply it by 10. And we will also multiply 10 to 45.78 making it 457.80.

(multiplying with 10 means shifting decimal to one right place. Multiplying by 1000 means shifting decimal to 3 right places)

Hence, the dividend will be 457.80 and divisor will be 17.

_____
1.7 | 45.78

ok....we want to make the 1.7 into a whole number....we do this by moving the decimal 1 space to the right.....and since we move the decimal one space on the divisor, we need to move the decimal 1 space on the dividend.

so ur problem would now be :
______
17 | 457.8
