Question

Solve the problem x - 8/5 equals 2/4

Answer 1

x = 2.1

Explanation:

1. Calculate 8/5 and 2/4 into numbers: 8/5 = 1.6, 2/4 = 0.5
2. Add 1.6 to 0.5: 1.6 + 0.5 = 2.1

Answer 2

Explanation:

x - 8/5 = 2/4

x = 2/4 + 8/5

x = 2*5/4*5 + 8*4 / 5*4

= 10/20 + 32 / 20

= ( 10+32 ) / 20

= 42 /20

= 21/10 = 2 1/10
