slater used 7 black legos and 21 green legos to build a tower what was the ratio of the number of black legos to the number of legos in the tower

Answer 1

The ratio of the number of black legos to the total number of legos in the tower can be calculated as follows:

Number of black legos = 7
Number of green legos = 21
Total number of legos = 7 (black) + 21 (green) = 28

Therefore, the ratio of black legos to the total number of legos in the tower is 7:28 or simplified to 1:4.
