The Eat Right Fruit Company sells 9/15 of a ton of bananas to one customer and 13/15 of a ton of bananas to another customer. Ho

Simora [160]

Since the problem is simply asking for the total tons of bananas the company sold, we can just simply add the tons of bananas the Eat Right Fruit Company sold to the two customers.

Doing this operation, we'll get:
$\frac{9}{15}+ \frac{13}{15}= \frac{22}{15}=1 \frac{7}{15}$

ANSWER: The company sold $1\frac{7}{15}$ tons of bananas.

Which ratio is proportional to 18/28 ? <br> Help me plzzzz i will give brainliest

maks197457 [2]

Answer:

18/21 = 30/35

Step-by-step explanation:

so the problem says 18/21 so if that's the correct ratio to proportion to the answer would be. 30/35. the reason is that you can divide 18 and 21 by 3 to get 6/7 then if you multiply by 5 you get 30/35. Dividing and multiplying both the denominator and numerator keeps the ratio proportional.
