Respuesta :
1. Make both denominators equal you need to multiply the numerator & denominator by the same number
3/4 *5
2/5 *4
2. After they are made the same you can just add the numerators together
15/20 + 8/20 = 23/20
3. Then you can simplify the answer in this case you can leave it as an improper fraction or change it to a mixed
1 3/20
