Answer:
1.) C
Because 18/27 and 6/9 both reduce to 2/3, while 12/15 does not.
2.) C
Because it's asking for the ratio of CPR training to first aid training. It's a trick question because though it mentions first aid first, and CPR training last, it's asking for you to find the reverse.
3.) C
Because to find the unit rate, the cost for each DVD, you divide 25.20, the total price, by 4, the number of DVD's purchased.
4.) B
Same thing as above.
5.) C
Same thing as the other two, but this time, you multiply the number you got from dividing the rate by time, by 2 since it wants to know how far Sheila went in 2 minutes.
6.) I cannot see the lower answer options but I believe the answer is 54.
He subtracted 130 from his account, added 240, then subtracted 56.
7.) B
Because 10/4 reduces to 5/2.
8.) C
Because 5/8 of 64 is 40, and 1/4 of 40 is 10. However, it wants to know how many players have classical solos, so look at the other 3/4 of 40; it is 30.
9.) I'm going to be honest, I dont know this one. Maybe post it seperately on Brainly, I'm sure someone will know what to do!
Have a good night and please do not be stressed out. Just truly do your best in math, and I promise you that if you care about it and work to understand it, it will all pay off in the end and you'll be astounded that you were ever confused! :)
Good luck!!!!
