Answer:
Hi! Here all you have to do is divided 6 into 1/4. You ultimate answer will be 24 hamburgers.
Step-by-step explanation:
There are two ways you could do this, either by dividing fractions or with decimals (I find decimals a little easier)
With fractions:
6 divided by 1/4
1/6*4
1/24
So there is 24 parts 6 can be divided into, or 24 hamburgers.
With Decimals
1/4= 0.25
6 divided by 0.25 = 24
ΔABC and ΔCBD are similar. Therefore we have the proportion:
![\dfrac{AB}{BC}=\dfrac{BC}{BD}\\\\AB=6;\ BC=x;\ BD=2](https://tex.z-dn.net/?f=%5Cdfrac%7BAB%7D%7BBC%7D%3D%5Cdfrac%7BBC%7D%7BBD%7D%5C%5C%5C%5CAB%3D6%3B%5C%20BC%3Dx%3B%5C%20BD%3D2)
Substitute:
<em>cross multiply</em>
![(x)(x)=(6)(2)\\\\x^2=12\to x=\sqrt{12}\\\\x=\sqrt{4\cdot3}\\\\x=\sqrt4\cdot\sqrt3\\\\\boxed{x=2\sqrt3}](https://tex.z-dn.net/?f=%28x%29%28x%29%3D%286%29%282%29%5C%5C%5C%5Cx%5E2%3D12%5Cto%20x%3D%5Csqrt%7B12%7D%5C%5C%5C%5Cx%3D%5Csqrt%7B4%5Ccdot3%7D%5C%5C%5C%5Cx%3D%5Csqrt4%5Ccdot%5Csqrt3%5C%5C%5C%5C%5Cboxed%7Bx%3D2%5Csqrt3%7D)
