Answer:
7:5
Explanation:
we will make the numbers 70 and 50 as low as they can be while still keeping the same ratio between the two numbers.
To do this we find the largest number that both 70 and 50 can be divided by. Then we divide both 70 and 50 by that number to get the new reduced ratio.
The largest number 70 and 50 can be divided by is 10. When we divide both numbers by 10, we get the new reduced ratio as follows:
7:5
