Answer:
<em>Ivan gets £90 more than Tanya.</em>
Step-by-step explanation:
The <u>ratio of Ivan and Tanya's shares</u> is ![4:1](https://tex.z-dn.net/?f=4%3A1)
Suppose, Ivan's share
and Tanya's share ![=1x](https://tex.z-dn.net/?f=%3D1x)
The <u>total amount of money</u> is £150. So, the equation will be.....
![4x+1x= 150\\ \\ 5x=150\\ \\ x=\frac{150}{5}=30](https://tex.z-dn.net/?f=4x%2B1x%3D%20150%5C%5C%20%5C%5C%205x%3D150%5C%5C%20%5C%5C%20x%3D%5Cfrac%7B150%7D%7B5%7D%3D30)
So, Ivan's share
and Tanya's share ![=1(30)=30](https://tex.z-dn.net/?f=%3D1%2830%29%3D30)
Now, ![120-30= 90](https://tex.z-dn.net/?f=120-30%3D%2090)
Thus, Ivan gets £90 more than Tanya.
