48 + 67 + 134 + 121 + 15 = 385
87 + 15 + 48 = 150
115 + 67 - 48 = 134
-48
150
18y+48+5y+15 = 270 18y+5y = 270-48-15 23y = 207 y = 9
8 + 6 = 14 and 40 + 80 = 120. So therefore 48 + 86 = 14 + 120 which is 134
7/8 + 5/6 = 42/48 + 40/48 = 82/48 = 134/48 = 117/24
2.7916666 repeating
86 + 48 = 134 25/27 + 11/27 = 36/27 or 1 and 1/3 134 + 1 and 1/3 = 135 and 1/3
20/48 + 15/48 = 35/48
The answer is 33. Simply add the numbers together arithmetically as you would for the problem two plus two. To check your work, a calculator is the best option.
86 + 48 = 134 25/27 + 11/27 = 36/27 or 1 and 1/3 + 134 = 135 and 1/3 2347/27 + 1307/27 = 3654/27 = 135 and 1/3
