<h3>Similar shapes</h3>
A rectangle is a quadrilateral that has 4 sides and angles.
If a rectangular shaped desk has a length of 30 inches and a width of 24 inches and a desk with a similar shape has a length of 48 inches, the width of the desk will be calculated using this expression;
l/w = L/W
30/24 =48/W
Cross multiply
30W = 24 * 48
W = 38.4inches
Hence the width of the desk will be 38.4inches

Answer:
1. x=69/40
2. x=3/4
Step-by-step explanation:
#1 steps
1. Convert the decimals to fractions
x/9/20 = 23/100/3/50
2. Simplify the fractions
20x/9 = 23/6
3. Simplify the equation using cross multiplication
6 * 20x = 23 * 9
120x = 207
4. Divide both sides by 120
x = 69/40
#2 steps
1. Simplify the fractions
1/3/1/6 = 3/2/x
2 = 3/2/x
2 = 3/2x
2. Multiply both sides by the equation 2x
4x = 3
3. Divide both sides by 4
x = 3/4
