Answer:
3 dollars
Step-by-step explanation:
4/15 of 30 = $8
2/5 of 30 = $12
7/30 of 30 = $7
8 + 7 + 12 = $27
30 - 27 = $3
They only had 3 dollars left after spending everything else they had.
Answer:
3/30
Step-by-step explanation:
4/15 so times 15 by 2 and 4 by 2 to get 8/30
leave 7/30 alone
2/5 five times 6 is 30, since you multiplied 5 by 6 you have to do 2 x 6 which is 12, 12/30
now you can add bc a common denominator 12 + 7 + 8 = 27
30 - 27 = 3, so 3/30ths was spent on souvenirs.
