When you divide 9 by 15, the result is 0.6. This means that 15 goes into 9 zero times with a remainder of 9. To express this as a decimal, you can perform the division:
9 ÷ 15 = 0.6
Alternatively, you can also express this as a fraction:
9 ÷ 15 = 3/5
Both 0.6 and 3/5 represent the same value, just in different forms. The decimal form is often used for simplicity in calculations, while the fraction form is useful for understanding the relationship between the numbers.
