21/30 + 8/30 = 29/30
four fifths is equal to eight tents, so three tenths plus eight tenths is eleven tenths, or one and one tenth
When adding 3 tenths and 4 tenths, you are essentially adding like terms. In this case, both numbers have the same unit (tenths), so you can simply add the numerical values together. Adding 3 tenths and 4 tenths gives you a total of 7 tenths.
Watch closely:7.4@above, yes, to elaborate, you are writing 7, and 40/100, which any fraction would go after the decimal point. so 7.40, you can also drop the 0
Question : How do you write two thousand seven hundred and four tenths in standard form ? Solution : We have 2700.4 = [(2700.4/1000) × 1000] = 2.7004 × 10³ (in standard form)
four tenths?
seven and eight tenths. you have to change one half to five tenths and then add the whole numbers and then the fraction

To add seven tenths to a number, multiply the number by 1.7. For example, 50 plus seven tenths of 50 is equal to 50 x (1 + (7/10)) = 50 x 1.7 = 85.

Each time, you add one to the numerator and one to the denominator.
four tenths?
2.9 (if you mean a decimal)
They add up to 19/20
Add the tenths together to get 13/10... This gives you 1 and 3/10... Now - add in the whole numbers from the original sum, and you get 4 and 3./10
Multiply two fifths by two to get a common denominator. Then you will have 4 tenths plus three tenths. then add straight across and you will get seven tenths.
