48 + 32 + 20 = 100 seedlings
Mango: [tex]\dfrac{48}{100} = \dfrac{12}{25}[/tex]
Mahogony: [tex]\dfrac{32}{100} = \dfrac{8}{25}[/tex]
Narra: [tex]\dfrac{20}{100} = \dfrac{1}{5}[/tex]
Mahogony + Narra: [tex]\dfrac{32+20}{100} = \dfrac{13}{25}[/tex]
Word problem: How much larger is the fraction of Mango seeds than Narra seeds?
[tex]\dfrac{12}{25} - \dfrac{1}{5} = \dfrac{12}{25} - \dfrac{5}{25} = \dfrac{7}{25}[/tex]
