Well, 11 + 7 = 18. 18/15 = 1 and 3/15 = 1 and 1/5.
First we convert them into similar units, giving us 10 fifteenths and 12 fifteenths. Together that is 22 fifteenths or 1 and 7 fifteenths.
three fifteenths
It is 1 1/30.
3 fifteenths minus 5 fifteenths equals minus 2 fifteenths.
Well, 11 + 7 = 18. 18/15 = 1 and 3/15 = 1 and 1/5.
12 fifteenths (sure?)19 fifteenths = 10 fifteenths (2/3) + 9 fifteenths (3/5)
1/5 + 3/15 = 1/5 + 1/5 = 2/5.
¹/₁⁵ ⁺ ⁹/₁₀ =²/₃₀ ⁺ ²⁷/₃₀ = ²⁹/₃₀
1/3 + 2/5 = 5/15 + 6/15 = 11/15 (Eleven fifteenths)
