Melinda rode her bike 54/100 mile to the library then she rode 4/10 mile to the store how far did Melinda ride her bike in all

So you have to add the fractions

54/100 plus 4/10 so the 10 have to become 100 like the denominator of the first fraction. So you have multiply 10 by 10 = 100 and then you have to multiply 4 by 10 = 40

so is 54/100 + 40/100 just add the 54 and 40 = 94

so the answer is 94/100

54/100 plus 4/10 so 4/10=40/100, 54/100 + 40/100 = 94/100
