Nicole collected 1/4 of a bin of glass bottles to recycle. Maggie collected 5 1/5 times as many bins as Nicole. How many bins of
mojhsa [17]
This is a multiplication problem, so you multiply 4 x 5 1/5. First change 5 1/5 into an improper fraction. Do this by multiplying the denominator and whole, then add the numerator. 5 x 5 + 1= 26. Improper fraction is 26/5. Now multiply 4 x 26/5. 4 x 26= 104. So it is 104/5. Now if you want a mixed number your answer is 20 4/5
