At Scobee Middle School, 35% of the seventh graders ride the bus to school. If there are 320 seventh graders, how many 7th grade
anzhelika [568]

Answer: 112 7th graders ride the bus .

Step-by-step explanation:

Given: The proportion of 7th graders ride the bus to school= 35% = 0.35  [to remove % we divide number by 100]

If there are 320 seventh graders, then the number of 7th graders ride the bus = 320 x (proportion of 7th graders ride the bus to school)

0.35 \times 320

= 112

Hence, 112 7th graders ride the bus .

Robin can clean 72 rooms in 6 days how many rooms can robin clean in 9 days
galben [10]

Hello!

Robin can clean 72 rooms in 6 days. How many rooms can Robin clean in 9 days?

We have a proportional magnitude (directly proportional), if we increase the number of days for cleaning, obviously we will have more rooms cleaned, then:

clean rooms __________ days

72 ----------------------------------- 6

y ------------------------------------- 9

\dfrac{72}{y} = \dfrac{6}{9}

multiply the means by the extremes

6*y = 72*9

6\:y = 648

y = \dfrac{648}{6}

\boxed{\boxed{y = 108}}\Longleftarrow(clean\:rooms)\end{array}}\qquad\checkmark

Answer:  

108 clean rooms in 9 days
