Answer:
Move the decimal so there is one non-zero digit to the left of the decimal point. The number of decimal places you move will be the exponent on the 10. If the decimal is being moved to the right, the exponent will be negative. If the decimal is being moved to the left, the exponent will be positive.
7.75 × 10^−3
Answer:
-4
Step-by-step explanation:
Each roll of tickets = 100 tickets
32 * 100 = 3200
3,200 tickets were ordered in all.
We are given numbers 7.3 and 0.002475 .
We need to determine if 7.3 and 0.002475 numbers are rational or irrational numbers.
Rational numbers are the numbers can be written in fraction form p/q.
Where p is numerator and q is denominator.
7.3 could be written as 73/10.
Therefore, it's a rational number.
0.002475 could be written as 2475/1000000 and it's also a rational number.
<h3>Therefore, 7.3 and 0.002475 both are rational numbers.</h3>
