Answer:

a = 30

Step-by-step explanation:

Given the following data;

a = 18

b = 3

This is a direct proportion question.

Therefore, a is directly proportional to b.

Mathematically, a = kb

First of all we would find the constant, k;

k = a/b

k = 18/3

k = 6

Now to find the value of a when b = 5

a = kb

a = 6*5

a = 30

Step-by-step explanation:

Given:

Length of the Kitchen shelf = 26 3/8 inches

Width of the Kitchen Shelf =  15 1/2 inches

Incorrect measurement of the length of the kitchen shelf = 25 inches

Solution:

The Actual length of the kitchen shelf is 26\frac{3}{8}

But she measured as 25 inches

So the error in the measurement will be

=>Correct length of the shelf - Incorrect length of the shelf

=> 26\frac{3}{8} - 25

Coverting the mixed fraction to fraction,

=> \frac{211}{8} - 25

=> 26.375 - 25

=>1.375
