See a solution process below:

We can rewrite this problem as: What is 35% of 180? "Percent" or "%" means "out of 100" or "per 100", Therefore 35% can be written as #35/100#. When dealing with percents the word "of" means "times" or "to multiply". Finally, lets call the number of seventh graders we are looking for "s". Putting this altogether we can write this equation and solve for #s# while keeping the equation balanced: #s = 35/100 xx 180# #s = 6300/100# #s = 63# There are 63 seventh graders registered in the soccer camp.

#63# students have registered.

You can solve this with a simple analogy. In #100# students #35# are registered. In #180# students #x# are registered. You do the cross multiplication and you get: #100x = 180*35# #100x = 6300# #x=63# So, #63# students have registered.

Eva Adamson · Answer

undefined To find the number of seventh graders registered in the soccer camp, multiply the total number of students by the percentage of seventh graders: $ 180 \times 0.35 = 63 $. Therefore, there are 63 seventh graders registered in the soccer camp.
