To determine if 4/9 makes the equations true, you have to solve the multiplications. If the result is the same as the given one, then 4/9 makes the equation true.
First equation:
![63\cdot x=28_{}](https://img.qammunity.org/2023/formulas/mathematics/college/prgvejjumnbiwn88m7hshf2xxod9xjd2oi.png)
![63\cdot(4)/(9)](https://img.qammunity.org/2023/formulas/mathematics/college/pcrer2rx32bjgnq0qus7j7mifyk5hky4i2.png)
To multiply a fraction by a whole number, you have to multiply the whole number by the numerator and then divide the result by the denominator:
![63\cdot(4)/(9)=(63\cdot4)/(9)=(252)/(9)=28](https://img.qammunity.org/2023/formulas/mathematics/college/d5gkr1m1k0yfnd2dlx9oz4ikd27e61o3rd.png)
The result is 28, which means that 4/9 makes the equation true. The answer is YES.
Second equation:
![25\cdot x=14](https://img.qammunity.org/2023/formulas/mathematics/college/pkq01b9iv6w2iecw0yujlmj8e00cxvta9f.png)
Multiply 25 by 4/9
![25\cdot(4)/(9)=(25\cdot4)/(9)=(100)/(9)\cong11.\bar{1}](https://img.qammunity.org/2023/formulas/mathematics/college/p3monxg7iczdqheo3zxn1ealtpvel8coxx.png)
The result is different from 14, which means that 4/9 doesn't make the equation true. The answer is NO.
