Question

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 1

It hard to divide by 1.7, so instead try moving the decimal to 17. Since you moved it to the right one, you also have to move it in 45.78

So it would be after the 7

457.80
