Express the fractions 3/4,7/16 and 5/8 with LCD

Nikitich [7]

The least common multiple of the three denominators is 16 because:

$4 \times 4 = 16 \\ 16 \times 1 = 16 \\ 8 \times 2 = 16$

Change the fractions so that each fraction has a denominator of 16.

$\frac{3 \times 4}{4 \times 4} = \frac{12}{16}$

$\frac{7 \times 1}{16 \times 1} = \frac{7}{16}$

$\frac{5 \times 2}{8 \times 2} = \frac{10}{16}$

____________________________________________________

$1. \frac{12}{16} \\ \\ 2. \frac{7}{16} \\ \\ 3. \frac{10}{16}$

Ierofanga [76]

Answer:

$\Longrightarrow: \boxed{\sf{5(5a+8)}}$

Step-by-step explanation:

Use the distributive property.

Distributive property:

⇒ 5*5=25

⇒ 5*8=40

Rewrite the problem.

⇒ 5*5a+5*8

Solve.

Multiply.

⇒ 5*5a=25a

⇒ 5*8=40

Rewrite the expression.

⇒ = 25a+40

Therefore, the correct answer is 5(5a+8).

I hope this helps! Let me know if you have any questions.

What is the area of one trapezoidal face of the figure?

Arturiano [62]

The area of a trapezoid, A, is the average of the lengths of the bases (B and b) multiplied by the height, h.

$A = \dfrac{(B + b)h}{2}$

$A = \dfrac{(3~in. + 1~in.) \times 1~in.}{2}$

$A = \dfrac{4~in. \times 1~in.}{2}$

$A = \dfrac{4~in.^2}{2}$

$A = 2~in.^2$
