Answer 1

Answer:

mark me brainlinest

Step-by-step explanation:

Let number of children be x

therefore No. of sweets received by each 405 child =405x

=> 405x=20%ofx

=>405x=x5

=>x2=405×5

=> x=405×5−−−−−−√

=81×5×5−−−−−−−−√=9×5=45

∴ Required no. of sweets received by each child = 40545= 9

Answer 2

Answer:

let total children be x

since 405 sweets are to be distributed among x children.

so, divide 405 by x

405/x

now, number of sweets received by each children is 20% of x

so,

405/x=(20/100)*x

(405*5)=x^2

x^2=2025

x=√2025

x=45 answer
