If a is three times b, b is twice c, and c is four times d, what is the value of \(\frac{a\cdot c}{b\cdot d} \)?
If a is three times b, b is twice c, and c is four times d, what is the value of ?
a = 3b therefore a = 3b = 6c = 24d
b = 2c b = 2c = 8d
c = 4d c = 4d
to determine a • c / b • d let's put everything in terms of one "letter" ... looks like d would be the easiest
24d • 4d 96d2
——–—— = ——— the d2 cancel out leaving 96 divided by 8 which is 12
8d • d 8d2
Same answer as the first guy, except I showed you how to get it.
