I was trying to increase the size of my Ubuntu(ext4) using Gparted, and while I managed to increase the size to 270GB I noticed that I have too much unallocated space. I am attaching the image below(sorry for the poor quality). As you can see I have created, foolishly, three ext4 partitions but the one that my Ubuntu uses is sdb5. Also, sdb4 and sdb7 are partitions for D and E of my Windows OS. Now, is this somehow possible to use all the unallocated space I have to be merged with ext4(sdb5)? I am ready to sacrifice D and E. Please help, I would be really grateful.
PS - please do not flag this as duplicate as I wasn't able to find a solution. Thanks.

A better plan is...
There is one rule you're forgetting you cannot have more that four primary partitions... So you have to delete one partition and create a new one that covers the entire space + unallocated
