Question

The ratio of girls to boys in a school is 6 : 7 and there are 448 boys. How many students are there in the school? *

Answer 1

Step-by-step explanation:

576=2×2×2×2×2×2×3×3

448=2×2×2×2×2×2×7

HCF =2×2×2×2×2×2=64

Hence the number of classes required,

=(64576)+(64448)

=9+7=16

Answer 2

Step-by-step explanation:

No. of girls =6x

No. of boys=7x

6x+7x=448

13x=448

x=448/13

x=34.46

so your sum is wrong.
