Answer:28

Step-by-step explanation:

4:3 = 7(total)

7=49

1=7

4=28(boys)

Answer 2

The number of boys in the athletics practice is 21 .

Step-by-step explanation:

Given as :

Total number of athletes at the practice = n = 49

The ratio of boys to girls = 4 : 3

Let The number of boys = x = 4 a

let The number of girls = y = 3 a

According to question

Total number of athletes = number of boys + number of girls

Or, x + y = 49

    4 a + 3 a = 49

Or,   7 a = 49

∴         a = $\dfrac{49}{7}$

i.e       a = 7

So,   The number of boys = x = 4 × 7 = 28

And  The number of girls = y = 3 × 7 = 21

Hence, The number of boys in the athletics practice is 21 . Answer
