M+n= 14, and 14/9 equals 1 and 5/9.
You just need to do cross multiplication.
If 3 cartoons cost 4.77 then 8 cost...
8×4.77÷3=$12.72 done!
Add 1/5 and 1/3. 1/3+1/5=
First get common denominator( 15), So 5/15+3/15= 8/15
Then you calculate what is left over which is 7/15
If you choose one person from the group, you have a 12/20 chance of them being a girl. Now, if the first person is a girl, we have one less girl and one less person to choose from. So, the new probability for the second person is 11/19.
Then, we multiply the chances
12/20 * 11/19
3/5 * 11/19
33/95
