Answer:
9:1
Step-by-step explanation:
Divide both the numerator and denominator by the GCD
81 ÷ 9
9 ÷ 9
Reduced fraction:
9:1
Therefore, 81/9 simplified to lowest terms is 9/1.
Answer:
17.9375 square yards
Step-by-step explanation:
Let us have a common unit
What we have here is the case of inches and ft
10 ft 3 inches
1 ft = 12 inches
so 3 inches is 3/12 = 0.25 ft
= 10+0.25 = 10.25 ft
15 ft 9 in
= 15 + 9/12 = 0.75 + 15 = 15.75 ft
So let us convert to yards ;
Mathematically, 3 ft = 1 yard
so 10.25 ft = 10.25/3 = 3.4167 yards
15.75 ft = 15.75/3 =5.25 yards
So the square yards would be the product of this two;
which is;
(10.25/3) * (15.75/3) = 17.9375 square yards
Answer:
Surface area = 252 inches^2
Step-by-step explanation:
Surface area = 2lw + 2lh + 2wh
2(2*8) + 2(2*11) + 2(8*11)
32 + 44 + 176 = 252
