She can put the rocks into,
2 groups of 19
Or one group of 38.
Answer:
6. 130/130.5
7. C, 14 pink roses and 26 red roses
8. A, 18 model cars and 27 model airplanes
9. $359.10
Step-by-step explanation:
Number 6 involves two potential answers because although 30% of 435 is 130.5 you cannot have half of a person at a baseball game.
So the first thing you would have to is to find a common denominator so a common denominator between 11 and 15 is 165. 3/11 * 15 =45/165 next you would do 7/15 * 11=77/165 no that both denominators are the same we add the numerator but the denominator stays the same so 45/165 + 77/165 = 122/165
and since it can't be reduced any more 122/165 is your answer.
hope this helps :)
