Find the unit rate.<br> 48 cupcakes in 6 boxes=cupcakes per box
natka813 [3]

Answer: 8 cupcakes per box

Step-by-step explanation: "Per box" means in 1 box, so we can rewrite the given statement using fractions as

<em>48 cupcakes/6 boxes</em> = <em>__ cupcakes/1 box</em>.

To find out what goes in the blank, notice that we

have a 1 in the denominator of our second fraction.

So we want to find a fraction that is equivalent

to 48/6 that has a 1 in the denominator.

If we divide the numerator and denominator of 48/6 by 6,

we get the equivalent fraction 8/1 or <em>8 cupcakes/1 box</em>.

So now we have <em>8 cupcakes/1 box = __cupcakes/1 box</em>.

So an 8 must go in the blank which means that the unit rate

for 48 cupcakes in 6 boxes is <em>8 cupcakes per box</em>.
