about 60 seventh-grade students like reggae music.
about 108 seventh-grade students like reggae music

About 36 seventh-grade students like reggae music.

Step-by-step explanation:

Given: When Henry surveyed 45 seventh-grade students at random in the school cafeteria, he found that 3 out of 15 liked reggae music.

Thus, the fraction of students who like reggae music

Let 'x' be the number of students who like reggae music out of 180 students .

If we use proportional reasoning, then

Hence, About 36 seventh-grade students like reggae music.

the square root of what number? if you add that, then someone will probably answer the question.

chemists are often responsible for designing a chemical reaction and analyzing the products obtained from it. one significant part of designing a chemical reaction is determining the amount of each reactant that is needed and the amount of each product that will be produced. in order to do so, chemists use stoichiometry, the quantitative relationships between reactants and products.
