Answer 1

Answer: between 8 and 0

Explanation:

In this kind of question, to make both the divisor and the dividend a whole number, just consider the number of figures after the decimal point in the dividend. So, since it is two figures,

45.78/1.7

Multiply both the numerator and the denominator by 100.

45.78 100

--------- x ------

1.7. 100

= 4578.0

--------

170.0

Therefore, the decimal point is going to be placed between the 8 and 0.

Answer 2

Explanation:

To make the divisor, 1.7, a whole number, multiply by 10.

Therefore, multiply 45.78 by 10.

457.8

The decimal place is between the 7 and the 8 .
