Simply -3 3/4 divided by 2 1/2

Dima020 [189]

Answer:

$=-1\frac{1}{2}$

Step-by-step explanation:

Given the following question:

$-3\frac{3}{4} \div2\frac{1}{2}$

In order to find the answer, we first convert the mixed numbers into improper fractions. Then we use KCF (Keep, Change, Flip) and solve.

$-3\frac{3}{4} \div2\frac{1}{2}$
$-3\frac{3}{4} =12+3=-\frac{15}{4}$
$2\frac{1}{2}=2\times2=4+1=\frac{5}{2}$
$-\frac{15}{4} \div\frac{5}{2}$
$-\frac{15}{4} \times\frac{2}{5}$
$15\times2=30$
$4\times5=20$
$=-\frac{30}{20}$
$-\frac{30}{20} \div10=-\frac{3}{2}$
$-\frac{3}{2}=3\div2=-1\frac{1}{2}$
$=-1\frac{1}{2}$

Hope this helps.

If the cos θ = 5/13 and tan θ = 12/5, what is sin θ?

nataly862011 [7]

Answer: 12/13....Remember the shortcut SOH CAH TOA ——> sin = opposite/hypotenuse, cos = adjacent/hypotenuse, and tan = opposite/adjacent...know that for this problem tells you that cos = 5/13 and tan = 12/5 so thus sin = 12/13 (opposite = numerator of tan, hypotenuse = denominator of cos)
