Answer:
69 green tiles
Step-by-step explanation:
Total proportion based on ratio of red to green tiles, 7:3=7+3=10
Fraction of red tiles=7/10=0.7
Fraction of green tiles=3/10=0.3
If red tiles of 161 represent 0.7, the whole surface requires
161/0.7=230 total tiles in Bastet filled
Green tiles=Total number of tiles- red tiles=230-161 green tiles=69 green tiles
Therefore, Katrina requires 69 green tiles
Ans=69 green tiles
