Answer:

In bold.

Step-by-step explanation:

6/6 = 9/a

So a = 9.

6/c = a/4.5

6/c = 9/4.5 = 2

So c = 3.

By similar triangles:

d/5 = 6/ (6+6+3)

d/5 = 6/15 = 2/5

So d = 2.

Also by similar triangles

b/5 = 12/15 = 4/5

So b = 4.

Answer: There are 108 hammers, and there are 36 screwdrivers. 36×3=108·

Step-by-step explanation: We know that there are more hammers than screwdrivers, so there are 36 screwdrivers but there are 3 times as many hammers so we multiply 36 by 3 to get 108.

90% of a number is x . What is 100% of the number? Assume x>0

mariarad [96]

Step-by-step explanation:

Let the required number be n

$\therefore \: \frac{90}{100} \times n = x \\ \\ \therefore \: \frac{9}{10} \\ \\ \therefore \:n = \frac{10}{9} x \\ \\ \therefore 100\% \: of\:n = \frac{10}{9} x \times 100\% \\ \\ = \frac{10}{9} x \times \frac{100}{100} \\ \\ = \frac{10}{9} x \\$

NOTE: A number is always 100% in itself.
