Question

What is 4/5 + 1/8 ? Add and simplify

Answer 1

`(4)/(5)` +
`(1)/(8)`

First, find the least common denominator (LCD) of the two fractions.
5: 5, 10, 15, 20, 25, 30, 35, 40
8: 8, 16, 24, 32, 40
The LCD is 40.
Second, make the denominators the same as the LCD. / Your problem should look like:
`(4x8)/(5x8)` +
`(1x5)/(8x5)`
Third, simplify so that the denominators are the same. / Your problem should look like:
`(32)/(40)` +
`(5)/(40)`
Fourth, join the denominators. / Your problem should look like:
`(32+5)/(40)`
Fifth, simplify. / Your problem should look like:
`(37)/(40)`

Answer as fraction:
`(37)/(40)`
Answer as decimal: 0.925
