If 45.78 ÷ 1.7 is written in long division form as so that the divisor is written as a whole number, where should the decimal point be placed in the dividend? between the 4 and the 5
between the 5 and the 7
between the 7 and the 8
between the 8 and the 0

ANSWER: Between the 7 and the 8

STEP-BY-STEP EXPLANATION:

1.7 | 45.78

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 your problem would now be :

17 | 457.8

$320 to $405

step by step explanation:

in one day he earns between $64 and $81

therefore if he works for 5 days, he will earn between 64 x 5 to 81 x 5

= $320 to $405
