Question

I need help with this .
George studied 1/4 hour on Monday and 3/8 hour on Tuesday. How long did he study altogether on both days?

___ hours

Answer 1

!/4 + 3/8

to add these u need to make the denominators the same

the LCD of 4 and 8 is 8

so 1/4 becomes 1*2 / 4*2 = 2 / 8

now we just add the numerators (top parts)
