A poster is 1.5 cm long and 7.5 cm wide. Which of the following is the ratio (in lowest terms) of the length and perimeter of the poster?
Perimeter = 2(L+B)
P = 2(1.5+7.5) = 18
Length:Perimeter = 1.5:18
L:P = 1:12
The length and width of a tape are 2 m and 28 cm. What is their ratio?
What is the new ratio obtained by adding 4 to the antecedent and 2 to the consequent of the ratio 3:8?
So, the new ratio would be 7:10.

What are the extremes of the proportion 9:3::36:12?
Extremes are the end terms. So, 9 and 12 area the extremes of the given proportion.
12:3::x:1 ⇒3x =12 ⇒ x = 12/3 = 4
In a proportion, product of extremes is equal to product of means.
(Since H.C.F. of 144 and 28=4)
25:10::10:4 10^{2}=25 × 4 [ Since b^{2} = ac ]
∴ 10 is the mean proportion.
If x : y : : y : z, identify the correct statement from among the following.
x:y::y:z ⇒y^{2}=xz
Fill in the box so that the three numbers,32 and 64 are in proportion.
