Two numbers are in the ratio 3:4 when 4 is added to each term their ratio becomes 10:13. Find the numbers.

1 answer:

7 0

So there’s 2 steps to this. First we subtract what was added on both sides. 10-4 : 13-4 and we get 6:9. This ratio is true, but is not in simplest form, since both numbers are divisible by 3. So after dividing both sides by 3, the answer in simplest form will be 2:3. The correct answer is 2:3

svlad2 [7]

Quantity of cheerios cereal in the smaller box Hannaford sold = 9 ounces

Cost of nine ounces of cheerios cereal = $2.50

Cost of one ounce of cheerios cereal :

$= 2.50 \: \div \: 9$

$=\color{plum}\$ 0.27$

Cost of one ounce of cheerios cereal in the smaller box = $0.27

Quantity of cheerios cereal in the larger box Hannaford sold = 20 ounces

Cost of nine ounces of cheerios cereal = $3.79

Cost of one ounce of cheerios cereal :

$= 3.79 \div 20$

$=\color{plum} \$0.18$

Cost of one ounce of cheerios cereal in the larger box = $0.18

Difference in their cost per ounce :

$= 0.27 - 0.18$

$=\color{plum}\bold{\$ 0.09}$

Therefore, the difference in cost in dollars per ounce between the two sizes = $0.09

so you basically just convert them
and you will times 30 by 6 to get 180, so you times 22 by 6
and you will get 132 problems

so Koby can do 132 problems
