• The ratio of ⬛ to △.
First count the number of ⬛ and the number of △ given.
We have:
Number of ⬛ = 45
Number of △ = 81
The ratio of ⬛ to △ = Number of ⬛ : Number of △
= 45 : 81
To Simplify the ratio, divide by the GCF which is 9.
= 45 ÷ 9 : 81÷9 = 5 : 9
Therefore the simplified ratio of ⬛ to △ = 5 : 9
• The ratio of △ to (⬛ + △)
81 : (45 + 81)
= 81 : 126
Simplify the ratio by dividing it with its GCF which is 9:
81 ÷ 9 : 126 ÷ 9 = 9 : 14
Therefore, the simplified ratio of △ to (⬛ + △) = 9 : 14
ANSWER:
⬛ to △ = 45 : 81 Simplified = 5 : 9
△ to (⬛ + △) = 81 : 126 Simplified = 9 : 14
