Question

Enter the missing numbers in the boxes to complete the table of equivalent ratios of lengths to widths.
Length (cm) Width (cm)
? 18
8 ?
10 30
12 ?

Answer 1

Answer:

As, ratio of length to width in each case should be same, as these are equivalent ratios of lengths to widths.

$1.\frac{x}{18}=\frac{8}{y}=\frac{10}{30}=\frac{12}{z}\\\\\frac{x}{18}=\frac{10}{30}\\\\ x=\frac{18}{3}\\\\x=6 cm \\\\2. \frac{8}{y}=\frac{10}{30}\\\\ y=24 cm \\\\ 3. \frac{12}{y}=\frac{10}{30}\\\\ y=12 \times 3=36 cm$

Length (cm) Width (cm)

?=6                18

8              ?=24 cm

10                30

12              ?=36 cm
