Question

Nter 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: Length (cm) Width (cm)

16 18

8 9

10 30

12 15

To find the missing values, we can use the fact that each ratio is equivalent.

For the first row, we can set up a proportion:

Length/Width = 10/18

Length = (10/18) * Width

Length = (5/9) * 18 = 10

For the second row, we can set up another proportion:

Length/Width = 12/x

x * Length = 12 * Width

x = 12 * Width / Length

x = 12 * 9 / 8 = 13.5

Rounding to the nearest whole number, we get x = 14.

Therefore, the missing numbers are 16 and 15.
