I'm pretty sure it would be 50°
4/10= 0.4
So if 0.4x10=4, That means that 4. Is 4/10 of 10.
4: 0.99
5: 0.66
6: 0.79
7: 5.2
8: 4.86
9: 4.3
I hope I helped! Also, one thing when you adding decimals or multiplying them, pretend the decimal point isn't even there. Then, once you have your answer, you just add the decimal in the middle. Basically just adding like in first grade! Super easy and I hope I helped!
