Answer: 3 balloons
Step-by-step explanation:
The ratio would be pink balloons to total balloons (aka pink/total), so 5 to 20 (aka 5/20). This simplifies to 1/4. If the new total is 12, and x represents pin balloons, then you can do 1/4=x/12. By cross multiplying, you get 12=4x. Divide both sides by 4 and x would equal 3. Therefore, the party store should expect to sell 3 pink balloons.
That is physicially impossible. Are you sure that is the correct question, or is it 77?
60•.30 is 28 60-18 is 42 times .15 is 6.3 and 42-6.3 is 35.7 so she will pay $35.70 as her final price
This is a problem on addition of dissimilar fractions.
1/3 + 3/5 = ?
To add dissimilar fractions, we have to convert it first to similar fractions. To convert to similar fractions, find the Least Common Multiple (LCM) of the denominators. In this case, LCM is 15. Then rewrite the fractions using the LCM as the denominator.
1/3 = 5/15; 3/5 = 9/15
Now proceed with the addition -
5/15 + 9/15 = 14/15
Then subtract the sum from the savings -
1 - 14/15 = 1/15
Therefore, Rachel still has 1/15 of her savings
