2 1/5 + 2 1/5 + 3 1/8 + 3 1/8​

First, express the mixed numbers as simple fractions:

2 1/5 = (2x5+1) /5 = 11/5

3 1/8 = (8x3+1)/8 = 25/8

11/5+11/5 +25/8 +25/8

22/5 + 50/8

LCM of 5 and 8 is 40

22/5 (8/8) + 50/8 ( 5/5)

176/40+ 250/ 40 = 426/40 = 213/20

As a mixed number:

213 divided by 20: 10.6500 =10

213 -(20 x 10)

10 13/20
