To add three tenths and four fifths, we need to find a common denominator. The least common multiple of 10 and 5 is 10. So, we convert three tenths to six twentieths and four fifths to eight twentieths. Adding these together gives us 14 twentieths, which simplifies to seven tenths. Therefore, three tenths plus four fifths is equal to seven tenths.
eight-tenths
9/10
one and five tenths or one and a half
4/5 plus 2/10 = 1
2/5 + 3/10 Make the denominator the same. 4/10 + 3/10 Add the numerator. 7/10
eight-tenths
4/5 is what a half plus three tenths equals.
the answer is 9
53/30 or 1 23/30
It's 2.3+4.2= 6.5
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.
9/10
one and five tenths or one and a half
One half is five tenths. Add three tenths, gives eight tenths. Simplify that by dividing the two values by their highest common factor, which is 2. That gives you four fifths.
4/5 plus 2/10 = 1
1 2/5
2/5 + 3/10 Make the denominator the same. 4/10 + 3/10 Add the numerator. 7/10
