Question 1. Brandon enters bike races. He bikes 8 $$\frac<1><2>$$ miles every $$\frac<1><2>$$ hourplete the table to find how far Brandon bikes for each time interval

Answer: 1 hour: 8 $$\frac<1><2>$$ + 8 $$\frac<1><2>$$ = 17 1 $$\frac<1><2>$$ hour: 17 + 8 $$\frac<1><2>$$ = 25 $$\frac<1><2>$$ 2 hour: 25 $$\frac<1><2>$$ + 8 $$\frac<1><2>$$ = 34 2 $$\frac<1><2>$$ hour: 34 + 8 $$\frac<1><2>$$ = 42 $$\frac<1><2>$$

Explanation: Divide the number of miles by the number of hours to find the unit rate in miles per hour. 3 $$\frac<1><2>$$ ? 1 $$\frac<1><4>$$ = $$\frac<7><2>$$/$$\frac<5><4>$$ $$\frac<7><2>$$ ? $$\frac<4><5>$$ = $$\frac<14><5>$$ Convert from improper fraction to the mixed fraction. $$\frac<14><5>$$ = 2 $$\frac<4><5>$$ miles per hour

Explanation: Divide the number of pages by the number of minutes to find the unit rate in pages per minute. $$\frac<5><8>$$ ? $$\frac<2><3>$$ = $$\frac<5><8>$$ ? $$\frac<3><2>$$ = $$\frac<15><16>$$ Thus Kenny read $$\frac<15><16>$$ pages per minute.

Explanation: Given randki hitwe that, A garden snail moves $$\frac<1><6>$$ foot in $$\frac<1><3>$$ hour. Divide the number of feet by the number of hours to find the unit rate in feet per hour. $$\frac<1><6>$$ ? $$\frac<1><3>$$ $$\frac<1><6>$$ ? $$\frac<3><1>$$ = $$\frac<1><2>$$ Therefore A garden snail moves $$\frac<1><2>$$ feet per hour.

Explanation: Given, A fertilizer covers $$\frac<5><8>$$ square foot in $$\frac<1><4>$$ hour. Divide the number of square feet, which is $$\frac<5><8>$$ by the number of hours, which is $$\frac<1><4>$$, to find the unit rate in square feet per hour. $$\frac<5><8>$$ ? $$\frac<1><4>$$ $$\frac<5><8>$$ ? $$\frac<4><1>$$ =$$\frac<5><2>$$ Convert from improper fraction to the mixed fraction. $$\frac<5><2>$$ = 2 $$\frac<1><2>$$ square feet per hour Thus A fertilizer covers 2 $$\frac<1><2>$$ square feet per hour.

Question 6. Brand A: 240 mg sodium for $$\frac<1><3>$$ pickle or Brand B: 325 mg sodium for $$\frac<1><2>$$ pickle. ____________

Answer: Find the unit rates in mg per pickle for each brand by dividing the number of mg by the number of pickles. Brand A: 240 mg ? $$\frac<1><3>$$ = 240 ? 3 = 720 Brand B: 325 mg ? $$\frac<1><2>$$ = 325 ? 2 = 650 650 is less than 720 so Brand B has a lower unit rate.

Answer: Find the unit rates in cups per serving by dividing the number of cups by the number of servings. Ingredient C: $$\frac<1><4>$$ ? $$\frac<2><3>$$ $$\frac<1><4>$$ ? $$\frac<3><2>$$ = $$\frac<3><8>$$ Ingredient D: $$\frac<1><3>$$ ? $$\frac<3><4>$$ $$\frac<1><3>$$ ? $$\frac<4><3>$$ = $$\frac<4><9>$$ $$\frac<3><8>$$ is less than $$\frac<4><9>$$, ingredient C has a lower unit rate.
