Answer:
4:3
Explanation:
4/7 means that there are 7 pieces in whole, and four of the are all ready shaded if you want to draw a shape and split it into 7 pieces. A ratio is similar to a fraction, but not the exact same thing. An example of a ratio would be 6 apple and 4 oranges. For every 6 apples that are added to the basket, there are 4 oranges added to the basket as well. to that means, there are 10 fruits being added to the basket every time, there are 10 pieces in whole.
So back to the problem, the ratio would be 7 pieces in whole, or 7 units because you would add 4 to 3 in the ratio 4:3, which is equal to 7 units in the fraction of 4/7.
