They are 10 boys and 4 girls tanking dance lessons. Write the ratio that compare the numbers of boys taking dance lessons to the total number to the students taking dance lessons

5:7

Step-by-step explanation:

There are 10 boys and 4 girls taking dance lessons

Therefore, the total number of students taking dance lessons is;

10 + 4 = 14

Now, ratio of boys to the number of students taking dance lessons will be:

Number or boys taking dance lessons : Total number of students taking dance lessons

this will give;

10 : 14

= 10 / 14

dividing the numerator and denominator by 2 to reduce to the lowest term

5 / 7

or 5:7

341

step-by-step explanation:

all you have to do is 9x31 (which equals 279) and then 20x31 (which equals 620). then you have to subtract. 620-279=341.
