Use repeated addition to find the solution to each multiplication problem. Change any improper fractions to mixed numbers. 4x1/3

Nata [24]

Answer:

$1\frac{1}{3}$

Step-by-step explanation:

Given the following question:

$4\times\frac{1}{3}$

To find the answer simply multiply the numerators and the denominators by each other.

$4\times\frac{1}{3}$
$4=\frac{4}{1}$
$\frac{4}{1} \times\frac{1}{3}$
$4\times1=4$
$1\times3=3$
$=\frac{4}{3}$
$\frac{4}{3} =4\div3=1\frac{1}{3}$
$1\frac{1}{3}$

Hope this helps.

What is the length of the diagonal of a 10 foot by 8 foot rectangle?

zloy xaker [14]

Diagonal of a rectangle formula:

Diagonal = √l² + w²
Diagonal = √10² + 8²
Diagonal = √100 + 64
Diagonal = √164
Diagonal = 12.806 feet.

Or you can use the pythagorean theorem. The diagonal of a rectangle is the hypotenuse of a triangle.

a² + b² = c² ; where a and b represents the lengths of the triangle and c is the hypothenuse. In this case, the lengths are 10 ft and 8ft.

10² + 8² = 100 + 64 = 164 ; This represents c².
c = √c² = √164 = 12.806 ft
