2. There are 50 sweets in a bag. 7 of the sweets are mangoes flavour. What percentage of sweets are mangoes flavour?

Jawaban dan Penjelasan

Berikut ini adalah pilihan jawaban terbaik dari pertanyaan diatas.

If 40% of the people in the classroom are girls, then the percentage of boys is 100% - 40% = 60%.

To find the number of girls in the classroom, we can multiply the total number of students by the percentage of girls:

Number of girls = 40% of 30 students = 0.4 x 30 = 12

To find the number of boys in the classroom, we can multiply the total number of students by the percentage of boys:

Number of boys = 60% of 30 students = 0.6 x 30 = 18

Therefore, there are 12 girls and 18 boys in the classroom.

To find the percentage of sweets that are mango-flavored, we can divide the number of mango-flavored sweets by the total number of sweets, and then multiply by 100 to convert to a percentage:

Percentage of mango-flavored sweets = (number of mango-flavored sweets / total number of sweets) x 100

Percentage of mango-flavored sweets = (7/50) x 100

Percentage of mango-flavored sweets = 14%

Therefore, 14% of the sweets in the bag are mango-flavored.
