What is the quotient of 4 1/4 / 2 1/5
Snezhnost [94]

The quotient for the given mixed fraction is 1.9318

Step-by-step explanation:

Step 1; First we must convert the mixed fractions into improper fractions. To do that the whole number is multiplied with the denominator and add with it the numerator while the denominator does not change. To convert this fraction 4\frac{1}{4} we multiply 4 with 4 and then add 1 and keep the 4 as the fraction's denominator so we get \frac{17}{4}. Similarly, we get the improper fraction \frac{11}{5} for converting the mixed fraction 2\frac{1}{5} .

Step 2; After conversion, it's just a matter of division. The fraction \frac{17}{4} equals 4.25 while the denominator \frac{11}{5} equals 2.2. Dividing 4.25 by 2.2 we get 1.9318.

Determine the rate and the unit rate. $279 for 9 tickets. $18 for 6 volleyballs. 4 fouls in 20 minutes. 36 strikeouts in 54 inni
sergejj [24]
<span>The rate is the ratio and the unit rate is the rate when the denominator is 1.


$279 for 9 tickets.

=> rate = $279 / 9 tickets => unit rate = $ 31/ ticket

 $18 for 6 volleyballs.

=> rate = $ 18 / 6 volleyballs =>  unit rate = $ 3 / volleyball

4 fouls in 20 minutes.

=> rate = 4 fouls / 20 minutes => unit rate = 0.2 fouls / minute

36 strikeouts in 54 innings.

=> rate = 36 strikeouts / 54 innings => unit rate = 0.67 strikeouts / inning
