1) Multiplicative inverses are the numbers whose product by the original number yields 1.
2) So examining the number 0.3 we can rewrite it as:
![(3)/(10)](https://img.qammunity.org/2023/formulas/mathematics/high-school/xv0i99tf245fjaur2vesfuk447ix9lp881.png)
3) And therefore the multiplicative inverse of that is the number:
![(3)/(10)*(10)/(3)=(30)/(30)=1](https://img.qammunity.org/2023/formulas/mathematics/college/bdmftythqs3p2y8fb1phjauuc3rqi2t7ra.png)
SO the multiplicative inverse of 0.3 is:
