Answer:
5:9
Step-by-step explanation:
One Simple Method:
We can plug in values that are reasonable, such as 5 and 9. 5 represents the amount of boys and 9 represents the amount of girls. There's four more girls than boys, adding up both terms there's a sum of 14 grandchildren.
Another Method:
using and creating an equation.
x represents boys
y represents girls
<u>Our equation for boys:</u>
x(x+4)=14
2x+4=14
<u>Subtract 4 from both sides</u>
2x=10
x=5
x=5 represents 5 boys.
Use x=5 in our equation for girls.
5+y=14
<u>Subtract 5 from both sides</u>
y=9
y=9 represents 9 girls.
