Answer:

number of boys = 320

number of girls = 240

Step-by-step explanation:

Total students in school = 560

Ratio of boys to girls = 4 : 3

Add the ratios together:  4 + 3 = 7

Divide the total by this number:  560 ÷ 7 = 80

Now multiply the original ratio numbers by 80 to find the numbers of boys and girls:

⇒ number of boys = 4 x 80 = 320

⇒ number of girls = 3 x 80 = 240

Total students are 560.

  • Let boys be 4x and girls 3x

[tex]\\ \rm\hookrightarrow 4x+3x=560[/tex]

[tex]\\ \rm\hookrightarrow 7x=560[/tex]

[tex]\\ \rm\hookrightarrow x=80[/tex]

  • Boys°320
  • Girls=240
